Issue

When we provide our own integer id to the repository for saving, it silently inserts an empty record with a generated ULID.

For example, providing an integer id like 1

album = await albumRepository.save(1, album)

will insert an empty record {} with a generated ULID album:01FJYWEYRHYFT8YTEGQBABJ43J - {} .

Expected Behaviour

The library should raise an error saying String expected for id or can implicitly convert the integer to string.
