Flow Errors

In many cases, flows fail because of an authentication error. If this type of error occurs, the error message includes the word "Unauthorized," or an error code of 401 or 403 appears. You can usually fix authentication errors by updating the connection.

1. You can view the connections by opening up the flow details by selecting the flow from My Flows.
2. Scroll to the connection that you saw the "Unauthorized" error message for.
3. Next to the connection, select the Verify password link in the message that states that the connection hasn't been authenticated.
4. Verify your credentials by following the instructions that appear. Then return to your flow-run failure, and select Resubmit.

Temporary issues

If error code 500 or 502 appears, the failure is temporary or transient.

• Select Resubmit to try to run the flow again.

Action configuration issues

Flows sometimes fail if a setting in one of the flow's actions doesn't work as expected. In this case, the error message includes the phrase "Bad request" or "Not found," or an error code 400 or 404 appears.

The error message should indicate how to fix the failure.

1. Select the Edit button, and then fix the issues inside the flow definition.
2. Save the updated flow, and then select Resubmit to try to run the flow again with the updated configuration.

Issues with your pricing plan

Sometimes your flows might behave unexpectedly because you aren't using the correct plan.
