I have one other webhook that DOES successfully fire, but no matter how many times I make another one on a different table, it simply DOES NOT FIRE.
The user reports that their database webhooks are not firing on a specific table, despite having another webhook that works successfully. They are seeking help to diagnose the issue.
Suggest you provide more detail. Check Postgres error logs. What does the hook do? Does the operation it is on succeed? Not much user help from what you have I suspect.
