Error when insertOne

[avalero]

Hello, if I try to insertOne with this Document

{
    "name": "Colegio Velazquez",
    "address": "Pl. Mayor, 2",
    "population": "Madrid",
    "phone": "917511520",
    "email": "velazquez@gmail.com",
    "type":["ACADEMY","CAMPUS"],
    "nature": "PUBLIC",
    "languages": ["español", "ingles", "aleman"],
    "contacts":[{"name":"Pedro", "email":"pedro@gmail.com", "phone":"333333333"}]
 }

I get the following error

api_bo_1    | error: Uncaught (in promise) TypeError: Cannot convert object to primitive value
api_bo_1    |         throw new BSONTypeError(`Unrecognized or invalid BSON Type: ${value}`);

Inserting that document directly from mongo shell results OK

The error is whith the objects array contacts as inserting

{
    "name": "Colegio Velazquez",
    "address": "Pl. Mayor, 2",
    "population": "Madrid",
    "phone": "917511520",
    "email": "velazquez@gmail.com",
    "type":["ACADEMY","CAMPUS"],
    "nature": "PUBLIC",
    "languages": ["español", "ingles", "aleman"],
    "contacts":[]
 }

works just fine

Testing I discovered the reason is because it expects and _id for any object (document), which should not be required (as it is not required by mongo).

This insertOne works just fine

{
    "name": "Colegio Velazquez",
    "address": "Pl. Mayor, 2",
    "population": "Madrid",
    "phone": "917511520",
    "email": "velazquez@gmail.com",
    "type":["ACADEMY","CAMPUS"],
    "nature": "PUBLIC",
    "languages": ["español", "ingles", "aleman"],
    "contacts":[{"_id": new ObjectId(), "name":"Pedro", "email":"pedro@gmail.com", "phone":"333333333"}]
 }

Closed because I cannot reproduce this with other inputs, there must be something on my input that makes it not work.
