I have set a column that sends a webhooks push notification when the column is changed. Today when I changed the column, I did not receive the webhooks push notification. Instead, I was prompted with the following message. I would like to know how to avoid this situation.

This webhook failed due to an
issue with the server. Please make
sure it's up and running.
              
I think I figured out the problem, it’s because my program didn’t return the data to the webhooks. So the push failed。
Thanks for your help
