Submitted variables in Task Complete does not show

I have created a Process with a user task.
I have sent in a Post - Task Complete with variables to Camunda rest engine.

GET /task/{id}/variables
I get a 200, but only {} back

can I view the history, to see that the variabels where persisted or can I view the variables somewhere in Camunda Cockpit
