Hello @jdewsnip,

thank you for your question and welcome to the prodigy forum!

Could you post an example of your .jsonl-file? I suspect that you might use the key "meta" with a string value in your data, for which Prodigy uses a dict as value. During the prediction, it tries to add a score to the meta-dictionary which could cause the error you see.
