Standard Logic App -SlidingWindow trigger - WorkflowRunActionInputsInvalidProperty In-line code cannot find csx file to run

Question

I'm encountering an issue with Azure Logic Apps when using the sliding window trigger. Specifically, my workflow fails with the following error:

WorkflowRunActionInputsInvalidProperty. The action '<action_name>' cannot find the csx file to run.

I have verified that the CSX file exists in my workflow folder using Kudu multiple times. Additionally, I have tried restarting the logic app, but the issue persists.

Interestingly, when I switch to the recurrence trigger, the problem disappears and the workflow functions as expected, without the CSX file access error.

Has anyone else experienced this issue with the sliding window trigger?

@Nepal, Ashesh ,

Thanks for reaching out.

The sliding window trigger in Logic Apps Standard can fail to find .csx files because it fires immediately, sometimes before the file system is fully initialized. This might cause a race condition where the script file isn't yet accessible. In contrast, the recurrence trigger waits for a scheduled interval, allowing the environment to fully load, which is why it works reliably with .csx files.
