[5.x]: afterSave Webhooks Error #97
Description
What happened?
Description
I'm in the process of upgrading my project from 4.x to 5.x. When trying to save an entry, I get this error related to the webhooks plugin (it's configured to run aftersave). I am running locally, and it seems to be caused by an unset environment variable used in the debounce and custom headers. Would it be possible to support missing env variables again? I would think that missing env variables should still allow the entry to save, and just the webhook might not work correctly.
Expected behavior
To be able to save entries without a webhooks error.
Actual behavior
