Hello tom 
I still can’t delete it, but it all seems to work without a web hook.
I don’t know what it is for.
I set up a bot in the organization that places the comments in the Merge Requests on GitLab and so on.
Would be nice to fix that strange state, or clarify the error description perhaps, but it’s nothing critical nor very relevant on our side (unless webhooks are really needed).
Thanks for your time!
