Shopify’s troubleshooting guidance distinguishes temporary errors from permanent ones, so a failed run does not automatically mean your workflow is misconfigured (Shopify’s Flow error troubleshooting guide). If a Shopify Flow workflow fails, open its run history first, identify the failed step and message, then classify the cause as data or configuration, permission, or a temporary execution problem. Fix the cause before using a manual retry, and check Shopify’s current eligibility conditions first.
This guide is for store operators who need to locate an error in an order, product, or customer workflow; administrators deciding whether to change access or configuration; and collaborators checking whether a problem is specific to the Shopify admin interface in a macOS browser.
Shopify Flow workflow failures: start with the run record
A useful run record narrows your next action. It can show whether the workflow is still running or has completed or failed, and provide details about the steps taken. Don’t disable, rebuild, or repeatedly run a workflow before checking that information. Shopify explains how to monitor Flow runs and review their details.
Where do you find the reason a Shopify Flow run failed? Open Flow in the store admin, go to the workflow’s run history or monitoring view, and select the relevant run. Record the workflow name, run status, failed step, error message, and the resource involved. The exact labels or navigation may change, so use the current admin interface rather than relying on an old screenshot.
| What you see | What to check in the run details | First response |
|---|---|---|
| No run for the event you expected | Whether the trigger matches the event and whether a run was created | Check the trigger and event timing before changing later actions |
| A run is still in progress | Which step is active and whether the message indicates a delay or timeout | Wait if the run is progressing; investigate the active step if it remains stalled |
| A run failed at an action | The error text, action input, and resource data passed to that step | Compare the required action input with the trigger output |
| A run completed but the store result looks wrong | The run’s steps and the current state of the relevant store resource | Verify the actual order, product, or customer record separately |
A trigger defines the event that starts a workflow. Check that your expected event matches the trigger you selected; Shopify describes how Flow triggers work in its trigger documentation. A workflow that never started is a different problem from a run that started and failed halfway through.
Scenario: An order-handling workflow appears not to have sent the expected follow-up. If there is no run, investigate whether the relevant event matched the trigger. If the run exists but failed at an action, use the error and step details to inspect that action’s inputs. If the run completed, check the order and the downstream result; a “Completed” status alone does not prove that the business outcome was correct.
Data mismatch or missing resource: inspect the handoff between steps
An action can fail if it does not receive the resource or data it needs. A workflow may also pass a list where the next action expects one resource, or pass a resource type that the action cannot use. These are input and workflow-design problems; changing computers or browsers will not supply missing data.
| Error pattern | Likely area to inspect | Possible correction |
|---|---|---|
| Required value is empty | Trigger output and the variable used by the action | Confirm that the event provides the value, then map the correct field |
| Resource type does not match | The resource produced by the trigger or preceding action | Align the action with the actual resource type |
| A list is passed to a single-item action | Whether the previous step returns multiple resources | Decide whether the workflow needs a loop or a different action |
| A step works for some events but not others | Differences in the event data or resource state | Compare successful and failed run details without assuming every event has identical data |
Shopify’s error guidance is the reference for interpreting Flow-specific messages. Start with the failed step, then trace its input to the trigger or earlier action. Don’t add a loop just because an error mentions a list: first confirm that the workflow actually needs to process each item. A loop can change which resource is available to later actions, so review the downstream steps after changing the design.
How should you handle a Shopify Flow error caused by missing data? Compare the action’s required inputs with the values available in the failed run. If the trigger does not provide the needed resource, choose an event or action that does, when available. If an earlier step returns multiple resources, use a loop only when the intended result is to process each one.
Shopify provides a testing workflow for checking a workflow’s behavior. Use its workflow testing guidance to understand what the test can verify, but compare the test inputs with the failed run’s actual event data. A test that uses a different resource or value may not reproduce the original failure.
Permission errors: request the missing access instead of switching devices
A permission problem can stop you from opening Flow, testing or editing a workflow, viewing run details, or enabling a workflow. These symptoms point to different actions, but none is fixed by using another Mac or browser. The store’s access settings and the permissions required for the relevant data, app, or secret must be reviewed by someone with the authority to change them.
Shopify documents Flow-related staff permissions and the access requirements for working with the app in its staff permissions guide. Check which specific permission is missing, then ask the store administrator to grant only the access needed for your task. Avoid asking for broader access than the workflow requires.
Who should you contact when Flow reports a permission error? Contact the person who administers staff access or app permissions for the store. Include the exact action you were trying to perform, the error message, and whether the issue is opening Flow, testing, viewing a run, or enabling a workflow. That gives the administrator a concrete access question to check instead of a vague report that “Flow is broken.”
Separate access to the Flow interface from access to the underlying resource or connected app. You may be able to open a workflow but still lack permission to work with a particular store resource, app, or secret. Ask the administrator to check the requirement associated with the error, rather than changing the workflow to work around access controls.
A browser refresh or a different device can help investigate a display problem, but it cannot grant store permissions. If the error explicitly identifies access, resolve that with the store administrator before retesting.
Long runs and repeat failures: distinguish delay from a persistent fault
A long-running execution is not automatically a permanent failure. Read the run status and the message associated with the step before deciding whether to wait, change the workflow, or retry. A single server-side error also does not prove that your configuration is wrong.
When a workflow repeatedly takes a long time or fails around the same step, inspect the amount of data the workflow is asking an action to process, the scope of any query, and whether a loop expands the work. Large result sets and repeated processing can make a workflow harder to diagnose. Narrow the query or revise the flow only when the run details support that diagnosis; don’t remove conditions simply to make a run finish.
What should you check when a Shopify Flow run stays active or fails repeatedly? Check the active or failed step, its error text, the resources being processed, and whether multiple items are handled in a loop. Compare runs that used different inputs. If the error is temporary according to Shopify’s guidance, avoid treating one occurrence as proof of a permanent configuration defect. If the same step repeatedly fails, investigate its input and processing scope before retrying again.
Shopify Flow’s troubleshooting documentation helps distinguish errors that may be temporary from errors that need a correction. Use the specific message and run context to make that call. Don’t assume every timeout, server response, or repeated run has the same cause.
Manual retry: fix first, then confirm eligibility
A retry is appropriate only when the underlying issue has been addressed and Shopify’s conditions for manual retry are met. Review the current manual retry instructions before acting; don’t assume every failed run can be retried or that retrying will correct a flawed workflow.
| Situation after diagnosis | Next decision |
|---|---|
| The failed action used a missing or mismatched value | Correct the trigger, mapping, or workflow logic before checking retry eligibility |
| The user lacked required access | Ask the administrator to resolve access, then confirm whether the failed run is eligible |
| The error appears temporary and Shopify permits a retry | Follow Shopify’s retry steps and monitor the new run |
| The workflow completed but the store resource is incorrect | Verify and correct the resource itself; a completed run may not be the right item to retry |
| The run does not meet Shopify’s retry conditions | Follow the documented alternative rather than repeatedly attempting a manual retry |
Can you retry a Shopify Flow run after fixing the problem? Sometimes. First correct the cause, then confirm that the run and workflow meet Shopify’s current manual-retry conditions. Use the instructions for the relevant run, and inspect the new run record afterward. Do not infer that the original run has been safely replayed just because a retry control is available.
For a workflow that needs a controlled manual execution rather than replaying a failed run, check Shopify’s separate guidance on manually running a workflow. Manual execution and retry are different operations; choose based on the job you need to perform and the official instructions for that operation.
Use this checklist before you retry or change the workflow:
- [ ] Open the run details and record its status, failed step, error text, and affected resource.
- [ ] Confirm whether a run exists; distinguish a missing trigger event from a failed run.
- [ ] Compare the action’s required input with the data available from the trigger and earlier steps.
- [ ] Check whether the failing action expects one resource but receives a list or another resource type.
- [ ] If the error identifies access, ask the store administrator to check the relevant Flow, data, app, or secret permissions.
- [ ] If the run is slow or repeats failures, inspect the affected step, query scope, and any loop before changing the workflow.
- [ ] Correct the cause and check Shopify’s current retry conditions before attempting a manual retry.
- [ ] After the next run, verify both the run record and the actual store resource involved.
macOS browser issues: separate interface testing from Flow execution
A remote Mac can be relevant when you need to reproduce a Shopify admin display or interaction problem in a macOS browser. It does not repair a Flow server-side error, provide missing trigger data, or grant store permissions. Keep those diagnoses separate: use run details and Shopify’s troubleshooting path for workflow execution; use browser testing only when the issue is specifically about how the admin interface behaves in that environment.
If a problem appears only in a macOS browser, record the page, the action that reproduces the display or interaction issue, and what you see. Then compare it with the Flow run record. If the workflow reports a failed action regardless of the browser view, browser testing is unlikely to address the underlying execution error. For more guidance on checking browser-specific admin behavior, use the relevant resources in OSXPort’s guide library.
There is no verified OSXPort browser-retest record provided for this article, so this section makes no claim about a particular browser version, remote Mac configuration, or observed result. Treat a remote Mac as an optional test environment, not as a Flow troubleshooting shortcut.
Choose the fix that matches the evidence
The key decision is whether the run points to workflow data or logic, missing access, a temporary execution issue, or a browser-only interface problem. Run history helps identify the branch; the error details and Shopify’s current instructions determine what to do next. A successful retry still needs a check of the relevant order, product, customer, or other store resource.
If you currently rely on screenshots or a single local browser, you may not be able to reproduce a macOS-specific interface issue consistently; switching devices still will not fix server-side Flow errors or store permissions; and an unrecorded test is difficult for another operator to repeat. When you need a temporary, genuine macOS browser environment to check the Shopify admin interface, you can assess whether an OSXPort remote Mac fits that testing task. If the only failure is in Flow’s run record, stay with the official troubleshooting and retry path instead.
