Is Fine-grained Personal Access Tokens compotable to Checking out private repository

[enginterzi]

I don't get this to work. I have a private repo I need to check out and use in another private repo of the organization.
So, inside the workflow, I'm doing this:

- name: Checkout private repository uses: actions/checkout@v4 with: repository: username/private-repo-name ref: main token: ${{ secrets.PAT }}

Here is the error message I'm getting
Retrieving the default branch name Not Found - https://docs.github.com/rest/repos/repos#get-a-repository

It seems to be working fine when I use the "classic" tokens. I've set all the permissions to read and write for testing purposes, so there should be no issues there.

I am considering the following points:

1. As this is still in beta, it may not be suitable for use in production.
2. There might be a bug with actions/checkout or it may not be compatible.
3. There could be limitations for both pro and free accounts.
