401 Bad credentials error message when trying to get runner registration token

[mbzomowski]

Hey all, I've been getting the following error message on my runner set listener pod:

2024-02-02T17:56:19Z	INFO	auto_scaler	unable to create message session. Will try again in 30 seconds	{"error": "failed to get runner registration token on refresh: unexpected response from Actions service during registration token call: 401 - {\"message\":\"Bad credentials\",\"documentation_url\":\"https://docs.github.com/rest\"}"}

I'm attempting to use ARC for a specific repository (https://github.com/pytorch/xla), which is within the pytorch org. For authentication, I created an app within another organization (a personal one I created).

Does the authenticating app need to be created within the same org that the repo is under? The instructions under https://docs.github.com/en/actions/hosting-your-own-runners/managing-self-hosted-runners-with-actions-runner-controller/authenticating-to-the-github-api#authenticating-arc-with-a-github-app only say that the app has to be owned by an organization, but not necessarily the one that owns the repo you're trying to use ARC with: Create a GitHub App that is owned by an organization.
