# Fehlerbehandlung

Es gibt viele Situationen, in denen Sie einem Client, der Ihre API benutzt, einen Fehler zurückgeben müssen.

Dieser Client könnte ein Browser mit einem Frontend, Code von jemand anderem, ein <abbr title="Internet of Things – Internet der Dinge: Geräte, die über das Internet Informationen austauschen">IoT</abbr>-Gerät, usw., sein.

Sie müssten beispielsweise einem Client sagen:

    }

    /**
     * Loads a crawler client into the specified crawler client factory.
     *
     * @param crawlerClientFactory the factory to which the client will be added
     * @param regex the regular expression used to match URLs for this client
     * @param componentName the name of the component to be loaded as a client
     */

                .normalizer(normalizer)
                .build(runner.client(), id);

        assertEquals(runner.client(), suggester.client);

        SuggestSettings settings = suggester.settings();
        assertEquals(settingsIndexName, settings.getSettingsIndexName());
        assertEquals(id, settings.getSettingsId());

     *
     * @param client the OpenSearch client used to clear the scroll context
     * @param scrollId the ID of the scroll context to be deleted; if null, no action is taken
     */
    public static void deleteScrollContext(final Client client, final String scrollId) {
        if (scrollId != null) {

The first part of the communication is just to establish the connection between the client and the server and to decide the cryptographic keys they will use, etc.

This interaction between the client and the server to establish the TLS connection is called the **TLS handshake**.
