I am trying to use Azure kuberenetes cluster and FluxCD to connect to a repository named realtimeapp-infra in Gitlab. I created the source and kustomization .yaml files in another repo training-setup, but getting the following error when I use flux get kustomizations in cmd. I was getting the same error with GitHub also. (I am new to both FluxCD and Kubernetes.)

EDIT: The problem was solved. It was due to no master branch in the repository, and I did not have access to create the master branch. After the owner created it, the issue was resolved.
