Mongo Error E11000 get key name using node.js

I am creating an index whose having a unique index and I am trying to insert documents in that collection but using the insertMany option. I am also using Mongo Transaction also. When I am trying to insert a duplicate document in MongoDB it giving me the following index error:

MongoError: E11000 duplicate key error collection: demo.unique_values index: unique_name dup key: { : "1234", : "testing", : "en-us", : "number", : 400, : false }
    
  operationTime: Timestamp { _bsontype: 'Timestamp', low_: 1, high_: 1623229996 },
  ok: 0,
  errmsg: 'E11000 duplicate key error collection: demo.unique_values index: unique_name dup key: { : "1234", : "testing", : "en-us", : "number", : 400, : false }',
  code: 11000,
  codeName: 'DuplicateKey',
  '$clusterTime': {
    clusterTime: Timestamp { _bsontype: 'Timestamp', low_: 1, high_: 1623229996 },
    signature: { hash: [Binary], keyId: 0 }
  },
  [Symbol(mongoErrorContextSymbol)]: {}
}

it is giving me information about my unique index but I want the error key number field here so How I can get this?

Also as I am using MongoDB Transaction with insertMany query with ordered: false option but still it is showing error for a single field, not all fields which having duplicate values for e.g: https://docs.mongodb.com/manual/reference/method/db.collection.insertMany/#unordered-inserts.

I need all errors of Insert Many and in a proper format. I am using Transaction. When I am using insertMany without transaction and order false it gives me error like

it showing all failed fields details so How I get this using Transaction

Code sample

try{
let session = await adaptor.startSession({});
await session.withTransaction(async () => {
    await adaptor.updateMany("unique_values",
                    {
                        key:{{key}},
                        uid:{{uid}},
                        locale:{{locale}},
                        type_uid:{{type_uid}},
                        deleted_at:false
                    }, {
                        $set:{
                        deleted_at:true
                    }},{session})
                    await adaptor.insertMany("unique_values",[{

"key":"1234", "type_uid": "testing", "locale": "en-us", "path": "number", "value": "400", "deleted_at": false, }], {

                        ordered: false
                    },
                    
                    );
                    await adaptor.deleteMany("unique_values",{
                        key:{{key}},
                        uid:{{uid}},
                        locale:{{locale}},
                        type_uid:{{type_uid}},
                        deleted_at:false
                    },{session})
})
}catch(error){
    
}

Kindly help me!
