When using ipv6 and protocol `mongodb+srv` there will be an error:

events.js:263
EventEmitter.prototype.emit = function emit(type, ...args) {

I think this is a bug introduced by the code below(`lib/core/sdam/monitor.js:70`)

 

// TODO: refactor this to pull it directly from the pool, requires new ConnectionPool integration
const addressParts = server.description.address.split(':');
this.connectOptions = Object.freeze(
Object.assign(

{ id: '<monitor>', host: addressParts[0], port: parseInt(addressParts[1], 10), bson: server.s.bson, connectionType: Connection }

,
server.s.options,
this.options,

// force BSON serialization options

{ raw: false, promoteLongs: true, promoteValues: true, promoteBuffers: true }

)
);
