Hi Martin, I remember us having issues with an HttpClient upgrade and I think you are hitting something that we solved in the latest Camel 4.18.4 release camel_http_gzip_double_decompression_with_httpclient_5_6 <https://camel.apache.org/manual/camel-4x-upgrade-guide-4_18.html#_camel_http_gzip_double_decompression_with_httpclient_5_6>
Can you try upgrading to 4.18.4?
