What is the current behavior?
When running tsc on a file that contains a mongoose import I get the following error:

node_modules/mongodb/mongodb.d.ts:3296:5 - error TS2416: Property 'end' in type 'GridFSBucketWriteStream' is not assignable to the same property in base type 'Writable'.
  Type '{ (): void; (chunk: Buffer): void; (callback: Callback<void | GridFSFile>): void; (chunk: Buffer, callback: Callback<void | GridFSFile>): void; (chunk: Buffer, encoding: BufferEncoding): void; (chunk: Buffer, encoding: BufferEncoding, callback: Callback<...>): void; }' is not assignable to type '{ (cb?: () => void): this; (chunk: any, cb?: () => void): this; (chunk: any, encoding: BufferEncoding, cb?: () => void): this; }'.

If the current behavior is a bug, please provide the steps to reproduce.
Pull the following repository and run npm install and npm run start

What is the expected behavior?
No errors should appear

What are the versions of Node.js, Mongoose and MongoDB you are using? Note that "latest" is not a version.
Node.js -> 14.15.2
Mongoose -> 6.1.5

I also face this problem. Any ideas?

@danchistyakov @Francesco-Lanciana if you are using the latest version of @types/node try to downgrade to the v17.0.5, i had the same issue and this solution solves my problem

@wejd Yes, it's a problem in the mongodb node package caused by the latest version of @types/node as explained here: mongodb/node-mongodb-native#3088.

It has been fixed in the latest release, therefore I suggest mongoose should update it's mongodb dependency to 4.3.0

Peg @types/node to < 17.0.5. The issue with this repo is that, for some reason, your lockfile pulls in @types/node@17.0.7 even though Mongoose 6.1.5 enforces < 17.0.5.
