      When using JSON Schema validation on a collection, the error returned by the server does not contain any information about which fields didn't match the schema.

      Steps to reproduce

      1. Create a collection with a JSON Schema validator:

      db.createCollection('testschema', {
  validator: {
    $jsonSchema: {
      bsonType: 'object',
      properties: {
        name: { bsonType: 'string' }
      }
    }
  }
})

      2. Try to insert a document which does not respect the schema:

       db.getCollection('testschema').insertOne({ name: 123 })

      Actual result

       2020-06-08T17:25:29.696+0200 E QUERY [js] WriteError: Document failed validation :

   "name" : 123
  }
})

      Expected result

      The error should contain information about which fields failed to match the validation schema.
