Error appears upon requesting PDF via webhook

We were receiving errors after receiving the webhook of a completed form, the system was immediately requesting the pdf using the previous methods. A week ago we started getting 501 timeouts.
my thought is build in a pause before requesting pdf. Potentially it is being assembled? We will try 3 minutes this week to see if it cures the issue.

Hello James,

Can you kindly provide us with more information about your workflow? Also, send the screenshot of the error messages to us as well as the link to your form so we can further check.
