Hello Claus, While camel-graphql component doesn't document this https://camel.apache.org/components/4.10.x/graphql-component.html, underlying class has following:
https://github.com/apache/camel/blob/main/components/camel-graphql/src/main/java/org/apache/camel/component/graphql/GraphqlEndpoint.java public void setHttpClient(CloseableHttpClient httpClient) { this.httpClient = httpClient; } can this be used to set up an http client that disables redirect as interim and let it "error"? Also it has a private method: private CloseableHttpClient createHttpClient() { HttpClientBuilder httpClientBuilder = HttpClients.custom(); if (proxyHost != null) { String[] parts = proxyHost.split(":"); String hostname = parts[0]; int port = Integer.parseInt(parts[1]); httpClientBuilder.setProxy(new HttpHost(hostname, port)); } if we can add a parameter to disalble redirect handling https://hc.apache.org/httpcomponents-client-4.5.x/current/httpclient/apidocs/org/apache/http/impl/client/HttpClientBuilder.html#disableRedirectHandling() and invoke it in createHttpClient - it can possibly prevent a direct from occurring. Trying regular http route: import org.apache.camel.builder.RouteBuilder; public class Workaround extends RouteBuilder { @Override public void configure() throws Exception { from("timer:java?period=1000") .setBody() .simple("Hello Camel from ${routeId}") .to("http:// https://swapi-graphql.netlify.app/.netlify/functions/index";) .convertBodyTo(String.class) .log("${body}") .log("${headers}"); } } Returns following: 2025-08-23 11:43:06.161 INFO 35408 --- [ main] e.camel.impl.engine.AbstractCamelContext : Apache Camel 4.13.0 (Workaround) started in 430ms (build:0ms init:0ms start:430ms boot:3s505ms) 2025-08-23 11:43:07.689 ERROR 35408 --- [ - timer://java] ocessor.errorhandler.DefaultErrorHandler : Failed delivery for (MessageId: F246E09A67CDCDC-0000000000000000 on ExchangeId: F246E09A67CDCDC-0000000000000000).
