Error for dancing-dots submissions

[ErikSchierboom]

When a submission to the dancing-dots exercise is submitted, it errors:

I'm trying to reproduce failures locally using the exemplar solution to dancing-dots and I can't.

I'm also confused about the stack trace of this error. The stack trace doesn't contain any files from the representer project, it's just all standard lib calls. But then again, maybe that's normal from an escript? However, the outermost function call, args_to_algebra_with_comments, does not appear in the representer's codebase 😕 we have Code.string_to_quoted! or Code.format_string! that could maybe be related?

False alarm, I reproduced it now 🙂 I didn't notice that this exercise has extra files in the lib besides the exemplar solution.
