Is there an existing issue for this?

Current behavior

Can not connect to the database when I use connectionName argument, I get " Unable to connect to the database. Retrying (1)" error.

Minimum reproduction code

Can not provide databse connection

Steps to reproduce

Use this module to connect to the databases:

import { Module } from '@nestjs/common';
import { ConfigModule, ConfigService } from '@nestjs/config';
import { MongooseModule, MongooseModuleOptions } from '@nestjs/mongoose';
import { DatabaseConnection } from './types';

@Module({
	imports: [
		// MongooseModule.forRoot('mongodb+srv://<user>:<pass>@<host>/<db>', {
		// 	connectionName: DatabaseConnection.TEST,
		// }),
		MongooseModule.forRootAsync({
			imports: [ConfigModule],
			useFactory: async (configService: ConfigService): Promise<MongooseModuleOptions> => {
				const protocol = configService.getOrThrow<string>('MONGO_PROTOCOL');
				const username = configService.getOrThrow<string>('MONGO_USERNAME');
				const password = configService.getOrThrow<string>('MONGO_PASSWORD');
				const host = configService.getOrThrow<string>('MONGO_HOST');
				const port = configService.get<string>('MONGO_PORT');
				const database = configService.get<string>('MONGO_DATABASE');

				const uri = `${protocol}://${username}:${password}@${host}${port ? ':' + port : ''}${database ? '/' + database : ''}`;
				console.log(uri);
				return {
					uri,
					// useCreateIndex: true,
					autoIndex: true,
					connectionName: DatabaseConnection.TEST,
					authSource: 'admin',
					replicaSet: '...',
					readPreference: 'primary',
					ssl: true,
					connectionFactory(connection, name) {
						console.log('NAME', name);
						connection.on('error', (error) => {
							console.log('DB connection failed! for error: ', error);
						});

						return connection;
					},
				};
			},
			inject: [ConfigService],
		}),
	],
	exports: [MongooseModule],
})
export class MongodbModule {}

Using simple forRoot works, but forRootAsync not. When I use forRootAsync without connectionName it also works. It don't provide any additional error logs

Expected behavior

Connect to database
