"Reponse variable name" value is lost when deploying via Modeler BPMNs with Http-Tasks (6.2.0)

I have several BPMNs with Http tasks.
When deploying these BPMNs (via xml or zip app) via modeler the “Reponse variable name” is lost (I rechecked the source code of the process in the xml and the value is there before to import it in modeler).

Is it a know issue? Any explanation?

I’m working with version 6.2.0.

That is indeed a bug you’ve hit. Fixed now here: https://github.com/flowable/flowable-engine/commit/2f8d08df80d3b19798f35bd2ba59e1268645f04f
