Integrate Circle CI with Github

Hi Team,

I have started using CircleCI recently. I was able to run pipelines earlier but now it suddenly started failing at checkout code step. Below is the error I am getting.

Using SSH Config Dir ‘/Users/distiller/.ssh’
git version 2.30.0
Cloning git repository
Cloning into ‘.’…
ERROR: Repository not found.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

I am fairly new to this and appreciate any help here.
