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:

=== "Pydantic v2"

    ```Python hl_lines="26-33"

// Here you should declare versions which should be shared by the different modules of buildSrc itself
val javaParserVersion = "3.18.0"
val groovyVersion = GroovySystem.getVersion()
val isGroovy4 = VersionNumber.parse(groovyVersion).major >= 4
val codenarcVersion = if (isGroovy4) "3.1.0-groovy-4.0" else "3.1.0"
val spockVersion = if (isGroovy4) "2.2-groovy-4.0" else "2.2-groovy-3.0"
val asmVersion = "9.7"

    *   Fixed bug in `tf.data.experimental.parse_example_dataset` when `tf.io.RaggedFeatures` would specify `value_key` but no `partitions`. Before the fix, setting `value_key` but no `partitions` would result in the feature key being replaced by the value key, e.g. `{'value_key': <RaggedTensor>}` instead of `{'key': <RaggedTensor>}`. Now the correct feature key will be used. This aligns the behavior of `tf.data.experimental.parse_example_dataset` to match the behavior of `tf.io.parse_example`....

En este caso el parámetro de la función `q` será opcional y será `None` por defecto.

!!! check "Revisa"
    También puedes notar que **FastAPI** es lo suficientemente inteligente para darse cuenta de que el parámetro de path `item_id` es un parámetro de path y que `q` no lo es, y por lo tanto es un parámetro de query.

!!! note "Nota"
    FastAPI sabrá que `q` es opcional por el `= None`.
