https://reqres.in/api/products - behaviors weirdly, responses are inconsistent

Parameter id theoretically works when used, but in reality, he changes the response body format

Normally:

https://reqres.in/api/products

Gives us: 
{
  data: Product[]
  page: number;
  per_page: number;
  total: number;
  total_pages: number;
}

When id used:

https://reqres.in/api/products?id=2

Gives us: 
{
  data: Product
}

Which response is equal to request:

https://reqres.in/api/products/2

To overcome this "bug", services.ts contains a condition that checks if id parameter was provided during fetch and parses the response to the right format.
Also parameter id causes to ignore other parameters like page

https://reqres.in/api/products?page=20&id=2

Also above request returns value (page value ignored)
