Problem 401 starting a new case in chrome browser


I have a 401 error when I start a new case from any process, this problem is to disallow the starting of any new task. Looking the trace of the requests APIs in chrome browser console, I realize the call to an API is triggering this error and the URL is this one:

Form data not passed to business variable

Hello All,

My process have a simple business object / variable. I have created a simple script that returns the new instance with the default values for the mandatory fields.

I have created an instantiation form with a simple text field, according to the contract defined for the instantiation step (object.attribute), but the value is never passed to the business variable. It's like the variables is instantiated AFTER the form as been invoked and submitted.

If I take a loot at the database, I see the default data returned in my script.
