Uploading image.png… Why test failed

These examples are intended to show some common error examples in the use of rest jaxrs, so they will cause some exceptions during execution, and then the test will fail. But this cannot pass the CICD test. I don’t have a good way to solve it yet. Are these use cases perhaps unnecessary?
