Fix ClosedResourceError

✅ Solution

"ClosedResourceError" in Starlette often arises when attempting to use a response (like a StreamingResponse) after it has already been closed, typically due to exiting the function or generator that originally created it. Ensure you're not accessing or iterating over the response's content after the initial function or generator has completed execution, such as trying to read the request body multiple times without proper handling of the stream. If using a generator, make sure it yields all necessary data before the function returns to prevent premature closure.
