Fix RequestValidationError
in FastAPI
✅ Solution
The "RequestValidationError" usually means your FastAPI endpoint expects data in the request body that is missing or doesn't match the expected schema. To fix this, carefully examine your pydantic model and ensure the incoming request includes all required fields with the correct data types. You can also use `Optional[]` for non-required fields in your Pydantic model.
