In the browser console is an error 500.

I’m not sure what this means or how to fix it. Everything looks fine otherwise.

I didn’t change anything but I created this “topic”, went back and tried it one more time, and it worked.

Summary

WHY NOT 2 MINUTES EARLIER

I changed some other little thing and now there is the same issue. Seems on and off randomly.

Are you the owner of the repository? Because the error does not come from n8n but rather from GitHub. The API returns a 404 if you try to listen to events of repository that you do not own. Here is another thread about that:

I do own the repo. I double-checked and I have spell everything correct.

I’m getting the same error

Hey all, unfortunately trigger problems are somewhat hard to debug as n8n doesn’t log the exact requests made when registering the webhook (which are what the GitHub trigger uses behind the scenes).

I’ve tried creating a bunch of GitHub triggers with manually added logging on my end but didn’t run into the problem, so couldn’t reproduce this unfortunately.

As a workaround, you can still register a webhook manually in your GitHub repository like so:

In n8n, make sure to use the right URL (production if you want your workflow to run in the background whenever active, check the documentation for details) and the POST method (which is what GitHub will use):

Finally, in GitHub paste the URL provided by n8n’s webhook node from the previous step and configure the other settings accordingly:

Hope this helps!

Is it because I’m running on Windows 10? I haven’t tried running in the cloud yet.

So your webhook URLs would need to be publicly accessible so GitHub (or any other service for that matter) can send it webhooks. If you expand the Webhook URLs section of the trigger node, does it by any chance show a localhost URL?

On Windows

Are you using the n8n Desktop version? Do you have a firewall that would block incoming requests?

Yes. I have already disabled the firewall and the error persists.

Testing each individual job works, after activating the flow the error appears.

Here’s some more evidence. This time upload an instance in the digital ocean.?
When I click on “Execute workflow” every flow runs fine. It just gives an error to make it active.
I can pass the test instance password for you to perform tests.

I am facing this issue also.

The workflow executes perfectly but when I try to activate it I get the Github Trigger: Not Found error.

It works great just clicking to execute the workflow on a one-time basis.

Morning,

I have created an internal ticket for this which we will be tracking as n8n-4757, As soon as I have an update I will let you know.
