please provide the stacktrace and exact error that you get to have a chance to get additional help. word seems to be your primary key so getting duplicates is unlikely. It's also unclear if you get the error in .get() or when .save() is called

If the error is that you are getting duplicates, make it retrieve the objects and log them in their raw format (print(list(db.NamedEntity.objects(word=entity).as_pymongo()))

@bagerard Sadly that's all there is, I'm using sentry to capture errors, so the exception shown above is all I have at the moment.
What's worse is I can't reproduce it. I'll add the print statement you suggested within the exception caught, and see what it returns.
Are save and get atomic? (I presume they are).

I suspect it isn't save, but get that actually triggers it, at least that's what the error seems to imply.
The environment is multithreaded using with concurrent.futures.ThreadPoolExecutor and my suspicion is that there is overlap in the code execution.
