When i try to update them with execution.setVariable it's returning me "null" and I need this variable to use a rest call task (I get a nullPointerException when I arrive to the rest call task)

Someone are using those variables ? What's their name ?

See my response to your other post.

Can you post your execute() method of your service task here?
