A user at Ursa Major Solar is experiencing a flow error while trying to process a record to the next status. The users with the same access can…

The problem is specific to one user, even though others with the same profile and permissions are unaffected. This indicates the error is related to the user's specific context or the data they are processing. The most effective troubleshooting step is to replicate the exact scenario. The debug feature in Flow Builder allows an administrator to run the flow as the specific user experiencing the error. This provides a detailed log of the execution path and reveals the precise point of failure and the reason for the error within that user's context.

B. Grant the user more data access by moving them higher in the role hierarchy: This is a potential solution, not a troubleshooting step. It's poor practice to grant more access without first diagnosing the root cause of the error.
C. Change the flow to run as System Context Without Sharing - Access All Data: This bypasses user permissions entirely, which might mask the underlying problem and create security risks. It doesn't help identify the cause of the user-specific error.
D. Grant the user the Modify All permission to ensure they have full system access: This is an excessive and insecure way to solve a problem. It does not help in diagnosing the specific reason for the flow failure.

In Flow Builder, you can enter values for the flow’s input variables and see the debug details as the flow runs... You can even debug the flow as another user."
