Issue adding a list of records to maprdb

When trying to add the following record:

elem = {"a": 0, "b": {"c": "d"}}
msg = {'_id' : 'vskjhg', 'elems': [elem]}

it is generating the following error:

Traceback (most recent call last):

mapr.ojai.exceptions.DecodingError.DecodingError: Encountered FIELD_NAME while looking for end object token.

My full code is

from mapr.ojai.storage.ConnectionFactory import ConnectionFactory

connection_string = "localhost:5678?auth=basic;user=mapr;password=mapr;ssl=false;"
connection = ConnectionFactory.get_connection(connection_str=connection_string)

def get_or_create(name):
    # Get a store and assign it as a DocumentStore object
    if connection.is_store_exists(store_path=f'/apps/{name}'):
        table = connection.get_store(store_path=f'/apps/{name}')
    else:
        table = connection.create_store(store_path=f'/apps/{name}')
    return table

elem = {"a": 0, "b": {"c": "d"}}
msg = {'_id' : 'vskjhg', 'elems': [elem]}
document_to_save = connection.new_document(dictionary=msg)

print(str(document_to_save.as_json_str()))

table = get_or_create('find_errors')
table.insert_or_replace(doc=document_to_save)

The object output by the print is below, it seems to have added an extra "$numberLong": 0 in the most nested dictionary {"_id": "vskjhg", "elems": [{"a": {"$numberLong": 0}, "b": {"$numberLong": 0, "c": "d"}}]}
