Your API almost always has to send a **response** body. But clients don't necessarily need to send **request bodies** all the time, sometimes they only request a path, maybe with some query parameters, but don't send a body.

To declare a **request** body, you use [Pydantic](https://docs.pydantic.dev/) models with all their power and benefits.

const (
	maxEConfigJSONSize        = 262272
	kubernetesVersionEndpoint = "https://kubernetes.default.svc/version"
	anonymizeParam            = "anonymize"
	anonymizeStrict           = "strict"
)

// Only valid query params for mgmt admin APIs.
const (
	mgmtBucket      = "bucket"
	mgmtPrefix      = "prefix"
	mgmtClientToken = "clientToken"
	mgmtForceStart  = "forceStart"
	mgmtForceStop   = "forceStop"
)

Their sponsorship also demonstrates a strong commitment to the FastAPI **community** (you), showing that they care not only about offering a **great service** but also about supporting a **robust and thriving framework**, FastAPI. 🙇

For example, you might want to try:

			return err
		}
	}
	if k.BatchSize > 1 {
		if k.QueueDir == "" {
			return errors.New("batch should be enabled only if queue dir is enabled")
		}
	}
	if k.BatchCommitTimeout > 0 {
		if k.QueueDir == "" || k.BatchSize <= 1 {
			return errors.New("batch commit timeout should be set only if queue dir is enabled and batch size > 1")
		}
	}
	return nil
}

// KafkaTarget - Kafka target.

        // their own environments if they really want to.
        if (BuildParams.isCi() == false) {
            return false;
        }

        // Only some hosts in CI are configured with Docker. We attempt to work out the OS
        // and version, so that we know whether to expect to find Docker. We don't attempt

    The upcoming Android Studio runs in a JVM but has classes from Android and that confused OkHttp!

 *  Fix: Don't crash on Java 8u252 which introduces an API previously found only on Java 9 and
    above. See [Jetty's overview][jetty_8_252] of the API change and its consequences.
