            Reporter: Francesco Spampinato


Hi, 

i have a simple route with http call to an oauth capable endpoint

 
{code:java}
from(timer("producer").period(2000).repeatCount(1))
  .setBody(constant("grant_type=client_credentials"))
  .setHeader(Exchange.CONTENT_TYPE, 
constant("application/x-www-form-urlencoded"))
  .setHeader(Exchange.HTTP_METHOD, constant("POST"))
  .to(http("https://my-oauth-host/as/token";)
    .authMethod("Basic")
    .authUsername("<client-id>")
    .authPassword("<client-secret>")
    .authenticationPreemptive(true)
    .logHttpActivity(false))
  .unmarshal().json(JsonLibrary.Jackson, Map.class)
  .log(LoggingLevel.INFO, LOG, ">> ${body}"); {code}
Oauth endpoint return gzip encoded responses as you can see from headers

 

 
{code:java}
HTTP/1.1 200 OK
Date: Tue, 07 Jul 2026 20:14:01 GMT
Content-Type: application/json;charset=UTF-8
Transfer-Encoding: chunked
Connection: keep-alive
Content-Encoding: gzip{code}
with parameter *logHttpActivity* set to false it works fine, if changed to true 
an exception is raised

 

 
{code:java}
