Warning: Failed to get nix-ci configuration from a nix-ci.nix file.
This may be because there is no nix-ci.nix configuration file, but we can't tell if that's the case or it is because there is an eveluation error; we cannot tell the difference.

Did not find the nix-ci.nix config file inside the repository, trying to find a 'nix-ci' output in the 'flake.nix instead.

Warning: Failed to get nix-ci configuration.
This may be because there is no nix-ci configuration (but we can't tell if that's the case), so continuing to build with the default configuration.

WARNING: If you are seeing a 'Cannot find Git revision' failure in a show job, be sure to configure git-ssh-key in your nix-ci configuration file.
