Description

When I create a generic function that receive a generic type D and D extends from AbstractSchema then I could not use FilterQuery<D> with any type

Steps to Reproduce

export class AbstractSchema {
  _id: any
  createdAt: Date
  updatedAt: Date
  deletedAt: Date 
}
export const generateExists = <D extends AbstractSchema = AbstractSchema>() => {
  const query : FilterQuery<D>= {deletedAt : {$ne : null}} // or {deletedAt : new Date()}
  //Typescript show error at query Type 'null' is not assignable to type 'ApplyBasicQueryCasting<QueryTypeCasting<D["deletedAt"]>> | undefined'
}

Expected Behavior

No response

Looks like a dup of #14459 / #14462.

Hi, I also encountered the issue in 8.3.0, but I don't think it's linked to classes, I have the same with a type:

export function setCreatedOnInFilter<Entity extends { createdOn: Date }>(
    mongooseFilter: FilterQuery<Entity>,
    someDate: Date,
) {
    mongooseFilter.createdOn = { $gt: someDate };
}

This yields the compile error (typescript strict mode on):

Type '{ $gt: Date; }' is not assignable to type 'Condition<Entity["createdOn"]> | undefined'.
  Types of property '$gt' are incompatible.
    Type 'Date' is not assignable to type 'ApplyBasicQueryCasting<QueryTypeCasting<Entity["createdOn"]>> | undefined'.
      Type 'Date' is missing the following properties from type 'QueryTypeCasting<Entity["createdOn"]>[]': length, pop, push, concat, and 29 more. ts(2322)

As hinted in this comment, it works in 8.2.2. TBH I'm not sure I understand how TS resolves the type condition to an array.

Same problem. In version 8.2.3 you broke backward compatibility.
