@loopback/repository 6.1.4 broke hasManyThrough relations

[ivanvaccari]

Describe the bug

After the release of @loopback/repository 6.1.4 about 6 hours ago, my hasManyThrough relations stopped working.

After a quite good amount of hours addressing the issue, got suspicious about this line: https://github.com/loopbackio/loopback-next/blob/master/packages/repository/src/relations/has-many/has-many-through.inclusion-resolver.ts#L271

Please note that i'm using mongodb and both ids, foreign keys are implemented via objectId. In one of the cases, the intersection fails when "targetEntityIds" is represented by a string array, while relatedIds is represented by a ObjectId array.
The intersecion fails, returning empty arrays.

Version 6.1.3 of @loopback/repository does not present the problem, i suspect it was introduced via commit 34f8201

Reproduction

Repository: https://github.com/ivanvaccari/lb4-HasManyThrough-test

Run the following sequence of rest calls:

1. POST /contact
   body: { "value": "johnwayne@gmail.com"}

2. POST /contacts/{previousContactId}/people
   body: { "name": "John", "age": "wayne"}

3. GET /contacts/{previousContactId}/people
   corectly return related models

4. GET /contacts
   filter: {where: {id: previousContactId }, include:[{"relation": "people"}]}
   Does not return correctly related models. Expecting the same output as of point 3.
