TypeScript Query.prototype.map() Mongoose 6

Bug

What is the current behavior?
Type definition of Query.prototype.map() stills present, even thought it is no longer part of mongoose 6, at least based on documentation, it also reports this.productModel.find(...).lean(...).map is not a function.

If the current behavior is a bug, please provide the steps to reproduce.

What is the expected behavior?
I suppose the Query.prototype.map() function has been removed from Mongoose 6 since it no longer on the documentation, if so it should also be removed from types definitions.

However, I used to use it and so I would like to know what is the alternative to transform the query result as I like, and that can be chained as a query helper and not set on the schema, and that runs after any post hook. Well, the question is, what is the replacement for Query.prototype.map().

What are the versions of Node.js, Mongoose and MongoDB you are using? Note that "latest" is not a version.
Node.js: 16.13.0
Mongoose: 6.1.4
MongoDB: 5.0.3

Hello @edgarbs1998

You need to change .map() to .transform()

See https://github.com/Automattic/mongoose/blob/master/CHANGELOG.md#600-rc0--2021-08-03

BREAKING CHANGE: rename Query#map() -> Query#transform() to avoid conflating with Array#map() and chaining #7951

Ref #11057

Hello @Kamikadze4GAME,

Thank you for your quick reply.
I have't found that change because it is not stated on the Migrating from 5.x to 6.x guide, so I believe it should be referenced there so it won't cause confusion to other people like it did to me.

It looks like I am unable to use the .transform() because its type definition is not on the index.d.ts yet.
I am quite new to TypeScript so, is there a way to fix the following TS error? Because my TS configs do not allow me to just ignore it.

Property 'transform' does not exist on type 'Query<(Document<any, any, Product> & Product & { _id: ObjectId; })[], Document<any, any, Product> & Product & { _id: ObjectId; }, {}, Product>'.ts(2339)
