"JSONDecodeError: unexpected character" on importer.import_annotations about darwin-py HOT 3 CLOSED

Hi @kevin-vitro,

This is almost certainly an actual invalidity in the JSON, or possibly a character encoding problem, given the error.

Currently, we've set multi CPU approaches off, as the error output we get from these when something does go wrong isn't what we'd like, and we have plans to implement a better version in future.

In the current version you should find the use_multi_cpu flag defaults to False

from darwin-py.

Yeah, I was able to figure that out, but it doesn't say which JSON is invalid so I had to do extra digging. My thought is that if we have an error raised doing this, it would be nice to have some idea which JSON file is bad in the list of N files.

You're right, and our plan is to implement better error reporting on the multiprocessing once we work on a new major refactor - the need for pickled functions obscures error output more than I'd like.

In the meantime, I'd try a simple script with a json.loads on the file you're trying to load, or putting the file into a JSON validator to source problems in it. IIRC, jq CLI tool can do this.
