Type 'Db' is not assignable to type 'DbTypes | Promise<DbTypes>'.

Describe the bug
After updating mongodb and mongoose packages, when I try to create new GridFsStorageInstance, this error appears:
Type 'Db' is not assignable to type 'DbTypes | Promise<DbTypes>'.

The full class is:

import { Injectable } from '@nestjs/common';
import { InjectConnection } from '@nestjs/mongoose';
import {
  MulterModuleOptions,
  MulterOptionsFactory,
} from '@nestjs/platform-express';
import { Connection } from 'mongoose';
import { GridFsStorage } from 'multer-gridfs-storage/lib/gridfs';

@Injectable()
export class GridFsMulterConfigService implements MulterOptionsFactory {
  private gridFsStorage: GridFsStorage;

  public constructor(@InjectConnection() private connection: Connection) {
    this.gridFsStorage = new GridFsStorage({
      db: this.connection.db,         // Type 'Db' is not assignable to type 'DbTypes | Promise<DbTypes>
      file: async (_, file) => {
        return new Promise(async (resolve) => {
          const filename = file.originalname.trim();
          const fileInfo = {
            filename,
          };

          resolve(fileInfo);
        });
      },
    });
  }

  public createMulterOptions(): MulterModuleOptions {
    return {
      storage: this.gridFsStorage,
    };
  }
}

Environment

• I'm using multer-gridfs-storage version 5.0.2

• My installed MongoDb version is 4.12.0

• I have Multer 1.4.5-lts.1 installed to upload files

• The Node version used to run the code is 16.16.0

• I'm (using/not using) Mongoose connection objects to create storage instances. The Mongoose version installed is (major.minor.patch)
