Dialog - "Error - Repository is read only"

[jhgoebbert]

In some situations this extension results in showing a dialog "Error: Repository is read only" if one wants to create a new "Untitled.ipynb" notebook by clicking in the launchpad on "Python 3".

I assume it comes from this lines of code:
https://github.com/jupyterlab-contrib/jupyterlab-gitlab/blob/main/src/contents.ts#L321

  newUntitled(options: Contents.ICreateOptions = {}): Promise<Contents.IModel> {
    return Promise.reject('Repository is read only');
  }

As soon as one has interacted with the filebrowser in some way, like creating a new file for example, this problem does not occur anymore. So I assume that the function "newUntitled" of the file-browser-plugin is called when a "Python 3"-notebook is newly created. And somehow the implementation of JupyterLab-GitLab is first in the row - which should not be the case.

I have seen this in JupyterLab 3.6 and now also in 4.2.1.

This might be a general issue with Contents.IDrive so I link this issue as reference: jupyterlab/jupyterlab#15143

The current work-around:
If you want to create a new notebook directly after restarting JupyterLab and do not want to open an existing one, you have to use the context menu of the file browser and not the buttons in the launchpad:

Thanks @jhgoebbert for reporting 👍

This is likely the same issue as jupyterlab/jupyterlab#15629, as this also happens with the jupyterlab-github extension.
