Also, for what it's worth, the error happened when in the diff from the main branch to the scalaError branch.

We'll need to minimise this.
It seems to me there's a lot of extra code in the repo, + a lot of dependencies, SBT plugins, etc.
Optimally, we'll need a minimised example with no dependencies.

@rleibman can you help?

Yeah, I know, unfortunately I don't have a lot of time to reproduce a minimal version, at least I know that it happens on that specific branch, so there's only a few files that are affected. I believe it's in one of the scala.js files, for what it's worth. I'm sorry if I can't be more specific and don't have much time to spend on it. I removed most of those changes from my main branch and can keep on working for now.
BTW, I understand if this is not enough to go on and you guys can't work on it, though there's always bugs that only show up in "real" code. Based on the error message, is there any ideas about what it could be?
