We have an usecase where we need to pass a string with "=" in it for payload for some reason stackstorm is not allowing me to do that, if i pass such value it is not taking it as a seperate string and causing multiple issues

Issue is not oberved if we are putting ":" instead of "=" and also putting a space after "=" solves the issue

Have tried different things (using jinja template replace option and replaced "=" with "= " but i am getting internal server error.
if i am able to pass the yaml validation, i can have my own validation in action py file but the issue the execution is not even going to the python file.

basically this should be accepted by stackstorm quasar create cluster_name=weekly_nats
