When an automation workflow is configured to perform an action based on a source folder or file, and that source folder or file is not found, the automation outcome will be logged as a failure.

In this case, check the Automation workflow and make sure the triggers and actions are configured properly and that the source folder and files exist. If the source folder and files exist, verify that access permissions are correct.

A missing source file error message can also indicate that a race condition occurred that caused the source file to be moved or deleted by another process.
