az ml job create not working anymore: "ERROR: Met error <class 'KeyError'>:'mlflow.source.git.branch'"

### Describe the bug

Since Thursday (03.07.2025) I get the error "ERROR: Met error :'mlflow.source.git.branch'" permanently when using the command "az ml job create". Unfortunately, I cannot say whether this also affects other commands.

### Related command

az ml job create -f job.yml --resource-group name-of-your-resource-group --workspace-name name-of-your-workspace --set something-to-set

### Errors

ERROR: Met error :'mlflow.source.git.branch'
