Hey @Yummi_Donut, welcome to the community. Have you tried disabling the Github trigger or the manual trigger once? Sometimes the workflow doesn’t know where to start and takes the wrong path . Otherwise: Is your username setup properly?
That error is coming back from Github, You need to set the git config options for the username and if it is a private repo you will also need to add the SSH key to your docker instance so it can be read from the git node.
The git node uses the git cli behind the scenes so it would be the same options you would normally need from a desktop when using it.
I am not sure what the git command line option would be for that. It is designed to be non interactive, the general advice I can find online recommends using ssh keys and I can’t see anything for passwords.
I would try mapping it as a volume to your container like you normally would to add files to any container then once set it should be a case of setting the git config item although you could try adding the key to the users home directory in the container which would be something like /home/node/.ssh/
