[Known issue] Your configuration specifies to merge with the ref 'refs/heads/master' from the remote, but no such ref was fetched

This message occurs now that the default branch has been renamed to "main", but your clone is still attempting to pull from "master".

To resolve this issue, run the following CLI commands in your local cloned repository:

```
git branch -m master main
git fetch origin
git branch -u origin/main main
git remote set-head origin -a
```

This will allow you to continue to pull the latest commits as usual.

Please refer to the announcement: https://github.com/aws/amazon-sagemaker-examples/discussions/3131

Start with the migration announcement in GitHub discussion #3131 and reproduce the reported message in a clone whose upstream still targets master. Verify the documented branch and remote commands, with completion shown by successful pulls from origin/main; no project file or test is named.
