Linear Oauth2 API credential fails with 503 error

What is the error message (if any)?

Once I authorize the app in the pop up, it redirects me to https://**-app.n8n.cloud/rest/oauth2-credential/callback and shows the following message:

#### Error: Request failed with status code 503

More details
Failed to connect. The window can be closed now.

This error only happens when the credential is used with the actor=app, however if I use user, it works just fine.

Please share your workflow

I don’t currently have a workflow as the problem happens when I am trying to authenticate to Linear from the credentials screen.

Information on your n8n setup

Sadly I have not been able to solve it

if you self host it, try adding the url with the port to the redirect urls in linear. i created two lines

https:// your-domain.tld/rest/oauth2-credential/callback
https:// your-domain.tld:PORTNUMBER/rest/oauth2-credential/callback

worked for me

Sadly I am not self hosting, but using the cloud version

I opened a PR about this: fix(core): Replace deprecated 'application' actor value with 'app' in Linear OAuth by adriencohen · Pull Request #20985 · n8n-io/n8n · GitHub

There is a temporary workaround

If you’re currently blocked, copy the OAuth URL opened by n8n, replace application with app, and continue the flow. It will work as expected.
