Cannot cancel process instance

I have simple process with one external service task. That external task has output parameter mapped like :
<camunda:outputParameter name="var1">${Vysledok}</camunda:outputParameter>

When I try to cancel running instance, I get an error:

It seems that is not possible to cancel process instance on activity with mapped output variables.

Hi @lucansky,

Your understanding is correct. I created a ticket for that: https://app.camunda.com/jira/browse/CAM-6749
Are you interested in providing that feature via a pull request?

Cheers,
Thorben

Thank you for quick response. I will wait when it gets into stable release.
