Error

google.api_core.exceptions.AlreadyExists: 409 ProductSet with ID 'test_set_4dc8450e-3a06-41fa-9ac4-086558f983a0' already exists.

I tried to reproduce this locally, but the test just passed.

The test is creating a product set and a product with the same id for every test.

The ids remain the same throughout the tests.

I think we can change the id per function to avoid this error.
