Introduction
TFE services listens to webhook and trigger run jobs in a VCS-driven workflow.
Scenario
As per Github documentation linked below "You can create up to 250 webhooks for each event on each installation target (GitHub Enterprise Server instance, specific organization, or specific repository)."
https://docs.github.com/en/enterprise-server@3.4/webhooks-and-events/webhooks/about-webhooks
If the webhooks limit have been reached, users will get an error as banner as below:
Error:
There was an error setting up your hook: The "push" event cannot have more than 250 hooks and Config must contain URL for webhooks.
Recommendation
Clean up the hooks in the repository to allow new creation of webhooks
