Function App sends 503 response after 30 seconds

Question

I'm developing a new PowerShell Function App, and when testing in the portal it succeeds in about 55 seconds, but returns a 503 error ("Service Unavailable") after 30 seconds, every time. If I comment-out enough of the code, it finishes in less than 30 seconds and returns a successful response. Is there an application setting I can add to force it to wait longer than 30 seconds before returning a response? Thanks!

Hi @MorganAdam-0661 ,

Thanks for reaching out to Q&A forum.

If your function is timing out after 50 seconds, you can increase the timeout value by specifying it in the host.json file.

If you want the powershell script to pause/wait for certain amount of time so that certain commands can complete its operation, then you can use the "Start-Sleep" command to suspend the activity in a script or session for the specified period of time.

Hope this helps! Feel free to reach out to me if you have any questions or concerns.
