I got an error with a stacktrace when trying to save annotations for a new dataset. The last few lines are

File "C:\NLP\venv\lib\site-packages\prodigy\recipes\ner.py", line 266, in   
doc.char\_span(span["start"], span["end"], label=span[label])  
TypeError: unhashable type: 'list'

The UI has a popup:

When I killed the process, I did get the message  
✔ Saved 8 annotations to database SQLite

However, when I tried a db-out for the dataset, no file was created, and the message said there were no annotations.

The error message was not helpful. I think the error was because I had the --update flag on. Removing it seemed to resolve the error. Shouldn't the dataset be created if it didn't exist?

Thanks for the report! It looks like this should be `label=span["label"]` instead. I've already fixed this for the next release. In the meantime, you can also add this in yourself by editing the line in `recipes/ner.py` (you can run `prodigy stats` to find the location of your Prodigy installation).

**Edit:** Just released a new nightly that fixes the problem:
