bson.errors.InvalidBSON: objsize too large after update_one

[rewiaca]

Getting this error when making any operation after editing database. Using lmdb. Guessed it was after wrong update_one, but not sure about. Anyway, adding original code of editing db:

    record = {'free': 12313232, 'path': '/media/mnt/'}
    col = getattr(db, 'storages')

    record = {**models['storage'], **record}
    if col.count_documents({'path': record['path']}) > 0:
        col.update_one({'path': record['path']}, {'$set': {**record}})
    else:
        col.insert_one(record)

Error text:

That's how db looks like in plain:

Does it stores changes after updating?

Hi, @rewiaca
The example code you gave does not define what variable models is, and could not reproduce the error at my end.

record = {**models['storage'], **record}

Could you update the example code ?

@davidlatwe Guess it's resolved with 2.3.9 update. Thanks for being reactive!
