TypeError on a PR with many commits

Bug report

What is the current behaviour?

In this PR I have hundreds of commits.

I'm guessing that the number of commits is the problem, I'm not certain.

On running the update-pull-request action I get the following error:

Perhaps over a certain number, the commit history is paginated meaning you don't get a string?

Note also that the stage where the error occurs is not the stage where it manifests: The error happens in the previous supposedly successful step

What is the expected behaviour?

• The release notes compiler should exit with a non-zero code if it fails, so that the error is targeted to the right place
• The release notes compiler should work with a long list of commits

To reproduce

Use either that particular PR, or take any repository with a long list of commits, look way back in the history, and check out a branch from there. Then make a PR from main into that branch and run the updater on it.

Note: I've set this as a very low priority because it's unlikely to affect us often. It's more likely to hit people who use a trunk based development pattern (which I'm essentially doing in this particular case, due to a major overhaul).

@thclark has this happened again at all recently?
