Hi,
I must confess I do not understand the branching workflow you are following,
Json Task variables is a very interesting feature, why don't you add it into the master branch ?
Please, explain us.

Sorry for the delay. Thank you for the great feature. I have approved the PR. Please fix the failing build/tests before merging.

Hi there @yogeshrnaik! As these commits are from back in late August, they won't count towards the Camunda Hacktoberfest project. Would you be so kind as to remove the 'hacktoberfest-accepted' issue label?

@rutscs if you would be so kind as to sign the CLA, that would be amazing. Thank you both so much! Alternately, @svenrr or @yogeshrnaik can re-run the CLA bot to remove that user from the automated check if they are no longer a contributor to the project.
