Getting exception "java.lang.RuntimeException: Rest response already sent." while building REST service

faziluddinsk — Fri, 15 Nov 2024 23:39:14 GMT

I am currently working on building a REST service, and everything looks good, but in the final component tRestResponse which returns the response back to the client, errors out with below exception. I am currently in a limbo as to what can be done to fix it. Please help.

java.lang.RuntimeException: Rest response already sent.

Hi @Not defined Not defined , maybe you have multiple conditions checked so you have multiple responses

desactivate the tRestRespoonse and see in the last tLogRow if you have muliple responses and from wich flow they are.

Send me love and kudos

I my goodness... this is a terrible job design.

First of all please move all parts creating the response payload into a embed child job to allow testing it without using the webservice.

Indeed multiple responses for one request triggers exactly this exception.
