I can reproduce by add only two spaces at last line in any file.

Thanks for that insight, @not-an-aardvark.

It appears that this error is consistently thrown if the file ends in a new line with a space character. When I delete the space, the error goes away.

Unfortunately, this pre-existing codebase in which I’m working oddly seems to have a lot of files that end in a new line + space.
