Doesn't build after changing repo type from hg to git

I have a project on BitBucket which I changed from Mercurial to Git. I changed the repo URL in RTD accordingly.

The project now fails to build and doesn't supply an error message.

I tried creating a new RTD project for this repo and it built successfully. However after deleting my project and creating a new one with the same name, it still won't build.

An example of a failed build is the one with id 1524296.

I would think the project clone directory just needs to be deleted.

Cheers
