GitHub Importer fails to Import branches with workflows

I have a repository that has a workflow on its master branch. The workflow is a very basic one. (The sample workflow created when selecting “setup a workflow for yourself” on workflow creation).

I was using the GitHub Importer to Import the repository on a new private repository. However, I was receiving this error as the import was about the end.

And then I checked the new private repository where I targeted the import, the Repository is there but the branch/es that has workflows within it is missing.

Is there something that I’m missing or am I doing something wrong?
