Filter / UpdateFilter do not infer the correct type of Record values

XMLWordPrintableJSON

      What problem are you facing?

      `Filter` and `UpdateFilter` do not infer the correct type of `Record` values.

      What driver and relevant dependency versions are you using?

      • mongodb v4.8.1
      • typescript v4.7.4

      Steps to reproduce?

      import { Filter, PropertyType, UpdateFilter } from 'mongodb';

interface Foo {
  data: Record<string, boolean>;
}

const queryOK: Filter<Foo> = { "data.path": true };
// ^ OK
const queryFail: Filter<Foo> = { "data.path": 1 };
// ^ Fail - TS does not flag the wrong type of `data.path`

const updateOK: UpdateFilter<Foo> = { $set: { "data.path": true } };
// ^ OK - Expected
const updateFail: UpdateFilter<Foo> = { $set: { "data.path": 1 } };
// ^ Fail - TS does not flag the wrong type of `data.path`

type DataValueType = PropertyType<Foo, `data.${string}`>;
// ^ `unknown` - should be `boolean`
