pymongo: Document must be an instance of dict - pymongo

Question

Afternoon,
I'm facing a problem with pymongo, I'm not able to set up correctly the parameter to insert into MongoDB via insert_many(). I came across with de following error:
TypeError: document must be an instance of dict, bson.son.SON,
bson.raw_bson.RawBSONDocument, or a type that inherits from
collections.MutableMapping [while running 'Insere no MongoDB']
What am I doing wrong ?
class InsertMongoDB(beam.DoFn):
def process(self, element):
arqJson=json.loads(element)
client = MongoClient("mongodb://user:password#mkp-cr-marketplace-core.lcr88.gcp.mongodb.net/db-poc-base360?retryWrites=true&w=majority%20")
db = client['db-poc-base360']
db.tbPropostaSucesso.insert_many(arqJson)
# tbPropostaErro = db['tbPropostaErro']
# tbPropostaErro
resultado = 0
yield resultado
I receive a messagem from Google PubSub and forward it to a method called InsertMongoDB().
I don't know how to suit my massage, whose value is in a json format, to use it correctly in the insert_many().
When I debug my variable "arqJson" has :
The json that I'm using is :

2020/11/20:
At the moment I'm struggling with the format of arqJson that I need to use in the insert_one(arqJson).
I forgot to mention that my method InsertMongoDB receives the arqJson from another method called InsertPostgreSQL.
InsertPostgreSQL does:
Receive the message from Pubsub;
-Transform the element : json.dumps(json.loads(element))
Save it into arqJson. After that, InsertMongoDB is called.
At this moment, I don't know how to format "element" (whose type is list) and save it into arqJson, because I have this error:
raise TypeError("%s must be an instance of dict, bson.son.SON, "
TypeError: document must be an instance of dict, bson.son.SON,
bson.raw_bson.RawBSONDocument, or a type that inherits from
collections.MutableMapping [while running 'Insere no MongoDB']
Thank you,

Answer 1

The solution is :
The first error is because your JSON contains a single document not
multiple docs for an insert many. If you use brackets like this
db.tbPropostaSucesso.insert_many([arqJson]) and convert it to a list
with a single element it will work. Or you can try
insert_one(arqJson). – DaveStSomeWhere 5 hours ago

I had the same problem, and what worked for me was adding retryWrites=false to the connection URL:
mongodb+srv://user:pass#server/etc...etc?retryWrites=false
