Describe the problem/error/question

so basically, I get an error trying to either run or test the workflow, and this happens out of nowhere, like, the process was running just fine yesterday, and now today with 0 changes made, it started giving this error

What is the error message (if any)?

i also searched on Github for generic errors like this but I think all the tickets have been closed.

i’ll put them here, they can still help:

I actually found out how to solve the issue but I don’t still exactly know why it’s happening, when I navigate to the github repo and go to settings to check the webhooks, I see some URLs that are already there, if I delete all of them, it wroks

This mainly happens when I “Test Workflow” and I do it multiple times without clearing? (clicking the dumpster icon) unsure… because sometimes it happens and other times no

I did some research about it and I found something along the lines of “n8n is trying to probe a new request to github repo but since the request is already there, it can’t generate a new one thus making it invalid”, which then if I delete the old request (the webhook URL) it will start working again

However like I said, the issue keeps presisting and it’s very counter intuitive to just keep going to the repo everytime the same problem happens and delete the webhook URL all the time
