**FastAPI** faz uso dele para que você veja o erro no seu log, caso você utilize um modelo de Pydantic em `response_model`, e seus dados tenham erro.

Contudo, o cliente ou usuário não terão acesso a ele. Ao contrário, o cliente receberá um "Internal Server Error" com o HTTP status code `500`.

 Optional supplemental description.
```
+ Make sure you have added the necessary tests (JUnit/[Core IT tests][core-it]) for your changes.
+ Run all the tests with `mvn -Prun-its verify` to assure nothing else was accidentally broken.
+ Submit a pull request to the repository in the Apache organization.
+ Update your JIRA ticket and include a link to the pull request in the ticket.

## Konzepte des Deployments

Obige Beispiele führen das Serverprogramm (z. B. Uvicorn) aus, starten **einen einzelnen Prozess** und überwachen alle IPs (`0.0.0.0`) an einem vordefinierten Port (z. B. `80`).

Das ist die Grundidee. Aber Sie möchten sich wahrscheinlich um einige zusätzliche Dinge kümmern, wie zum Beispiel:

* Sicherheit – HTTPS

func (listener *httpListener) start() {
	// Closure to send acceptResult to acceptCh.
	// It returns true if the result is sent else false if returns when doneCh is closed.
	send := func(result acceptResult) bool {
		select {
		case listener.acceptCh <- result:
			// Successfully written to acceptCh
			return true
		case <-listener.ctx.Done():

                    result.acceptedApiChanges.sort((a, b) => { 
                        if ((a.type +'#' + a.member) > (b.type + '#' + b.member)) {
                            return 1; 
                        } else {
                            return -1;
                        }
                    });

			tracker.RetryAttempts, tracker.ItemsHealed, tracker.ItemsSkipped, tracker.ItemsFailed)
	} else {
		if tracker.RetryAttempts > 0 {
			healingLogEvent(ctx, "Healing of drive '%s' is complete, retried %d times (healed: %d, skipped: %d).", disk,
				tracker.RetryAttempts-1, tracker.ItemsHealed, tracker.ItemsSkipped)
		} else {

			}

			if err == nil {
				if (test.expectedEndpoint.URL == nil) != (endpoint.URL == nil) {
					t.Errorf("endpoint url: expected = %#v, got = %#v", test.expectedEndpoint.URL, endpoint.URL)
					return
				} else if test.expectedEndpoint.URL.String() != endpoint.URL.String() {
					t.Errorf("endpoint url: expected = %#v, got = %#v", test.expectedEndpoint.URL.String(), endpoint.URL.String())
					return
				}

    try {

        assertFalse(from.exists());
