Build error: not our ref

Hello, I’m getting an inexplicable build error in my Hugo Academic site. This was triggered by a submodule change in Hugo Academic I believe.

Here are the details.

Domain and site name:
Github repository: GitHub - bshor/website

Here’s the error:

3:09:43 PM: Failed during stage 'preparing repo': From

Hiya @bshor ,

Sorry to say this is something in your code that will need a fix. We’ve seen it a half-dozen times over the years and never found a silver bullet for you to make the fix; but the article I have always pointed people to - and most did manage to make a fix using it - is this one:

Removing submodules entirely will also likely fix things if you want to do that instead - for hugo themes especially, you could always choose to clone into your repo and then remove the .git directory so you don’t track it explicitly; that’s what I do on my sites, to avoid the hassle of submodules and potentially debugging them.

Good luck!
