Challenge 2 / 2

After we fetch the ID as an array with Doctrine, why do we need to ensure it has a count of 1?

To make sure the array doesn't have duplicate IDs.

In case the multiple ID fields support different translation locales.

It's needed to verify the ID is stored as a string instead of an integer.

Because we need to make sure the entity only has one ID, otherwise it can’t be translated properly.
