• Update the GET /api/v1/products endpoint to accept and process the category query parameter.
• Users should be able to filter products by category while ensuring proper authorization checks.
• The endpoint should continue functioning as expected for clients not using the category filter.

when you set this condition what happens is query is not None?

Ohkay, your test fails

If query is none, then it gets all products;
if query is not none, it gets the product related to that category.
