	or when the ztunnel pod is restarted in the same pod (remove old entries when the same uid connects again, but with different boot id?)

So, with the same Python type declaration, **FastAPI** gives you data validation.

Notice that the error also clearly states exactly the point where the validation didn't pass.

This is incredibly helpful while developing and debugging code that interacts with your API.
