 Nevertheless, although we are not using the default integrated functionality, we are still using a Pydantic model to manually generate the JSON Schema for the data that we want to receive in YAML.
 
 Then we use the request directly, and extract the body as `bytes`. This means that FastAPI won't even try to parse the request payload as JSON.
 
 And then in our code, we parse that YAML content directly, and then we are again using the same Pydantic model to validate the YAML content:
