AWS CodeBuild with GitHub fine-grained personal access tokens

Question

I have created a CodeBuild project with the source configured to access the repository on GitHub. For that purpose I created a fine-grained personal access token. CodeBuild configuration was successful and a webhook has been created. Upon pushing a commit to the repo, a CodeBuild job is triggered.

However, the job hangs for 2 minutes on DOWNLOAD_SOURCE phase, and eventually fails with an error:
```
CLIENT_ERROR: authentication required for primary source and source version main
```

I kept adding more and more permissions, but didn't help:

Does CodeBuild have issues with fine-grained tokens? Any ideas what could be wrong?

I have exactly the same problem, even after granting all permissions it does not work and I get the message **CLIENT_ERROR: authentication required for primary source and source version main**

If I select the classic Tokens or oAuth it works. Unfortunately thats not what I would consider as least privilege. Any idea how we get fine-graded tokens to work?

OMG... I have spent days trying to figure out why this wasn't working, thinking it was something wrong with my setup. The fine-grained access token works when using a Github source for CodePipeline, but apparently not when configuring it as a source for a plain CodeBuild.

I cannot get oAuth to show any private GitHub repos, and using the connection is not an option for Codebuild.
I've wasted most of the day on this. Codepipeline, but that is not my requirement
