Prefect Community

hi there.  after adding a GitHub credentials block via UI, I updated my prefect.yaml pull section to `access_token: "{{ prefect.blocks.github-credentials.example-token }}"`  but my agent is unable to retrieve this properly and I receive a `"fatal: unable to access.. URL using bad/illegal format or missing URL"` message. what am I doing wrong here? thanks in advance

are you using a fine grained or regular github pat?

regular github pat.  if I leave access_token null then the agent prompts me for my creds.  once supplied the flow executes as expected.

got it. can you share your full pull step from prefect.yaml?

I don’t think we currently support the GitHubCredentials block for the pull step. 

instead - can you place your access token in a Secret block and reference that instead? That should work for you

ah interesting, yes the secret block did work.  thank you :slightly_smiling_face:
