Hi,
I'm wondering why I'm getting below error for one of my button action chain event in Visual Builder Studio extension. I checked my code I'm not using anywhere $packagepage.variables.

My simple logic on button event to update the variables which used to filter criteria of rest response.

and in filter criteria below is mapping.

All my variables are having common type that i define as Filter Criteria Type.

Please someone suggest solution why I'm getting this error. I tried to use $page.variables and direct access $variables both are not working and giving same error.
