Typescript types when using a map inside a schema

[almeidx]

Consider this example:

import { Document, Schema, model } from 'mongoose';

interface User extends Document {
  _id: string;
  roles: Map<string, string[]>;
}

const schema = new Schema<User>({
  _id: { required: true, type: String },
  roles: { of: Map, type: [String] },
});

const Users = model<User>('users', schema);

const level = 5;

Users.findByIdAndUpdate('abc', {
  $set: {
    /* Type '{ [x: string]: string[]; }' is missing the following properties from type 'Map<string, string[]>': clear, delete, forEach, get, and 8 more. */
    roles: { [level.toString()]: ['abc', 'abc2'] },
  },
});

Am I doing something wrong when updating a single entry on a map? If so, please let me know how to do it properly

And on a side note, I would rather have it be Map<number, string[]>, if possible, but if it isn't then that's completely fine.
