Mongoose unique error is now a MongoServerError not MongoError

[MarioVillar]

Hello,

From mongoose version 6 onwards, MongoError has been changed to MongoServerError. I think mongoose-beautiful-unique-validation plugin is not working for mongoose >= 6 version due to this change, as in the isUniqueError function just err.name === 'BulkWriteError' || err.name === 'MongoError' is checked.

I suggest adding MongoServerError to this condition. In case of any doubt, I leave the error log using mongoose 7.0.4:

MongoServerError: E11000 duplicate key error collection: followupusers index: email_1 dup key: { email: "[email protected]" } at node_modules\mongodb\lib\operations\insert.js:50:33 at node_modules\mongodb\lib\cmap\connection_pool.js:327:25 at node_modules\mongodb\lib\sdam\server.js:207:17 at handleOperationResult (node_modules\mongodb\lib\sdam\server.js:323:20) at Connection.onMessage (node_modules\mongodb\lib\cmap\connection.js:213:9) at MessageStream.<anonymous> (node_modules\mongodb\lib\cmap\connection.js:59:60) at MessageStream.emit (node:events:512:28) at processIncomingData (node_modules\mongodb\lib\cmap\message_stream.js:124:16) at MessageStream._write (node_modules\mongodb\lib\cmap\message_stream.js:33:9) at writeOrBuffer (node:internal/streams/writable:392:12) { index: 0, code: 11000, keyPattern: { email: 1 }, keyValue: { email: '[email protected]' }, [Symbol(errorLabels)]: Set(0) {} }

Thanks in advance.
