Fix ValidationError

in FastAPI

Solution

The "ValidationError: field required (type=value_error.missing)" error usually means your FastAPI endpoint expects a specific field in the request body, but it's missing or wasn't properly sent in the request. To fix this, ensure your request body includes all the required fields as defined in your Pydantic model associated with the endpoint, and verify that the field names match exactly. Also, check that the Content-Type header in your request is set to "application/json" if you are sending a JSON payload.
