SPIN Json variable not set properly when used as "in" variable in call activity ( V 7.12)

Hi All ,

I am using the SPIN library and setting the customer data in json variable called “Customer” . I am able to see the data in ACT_RU_VARIABLE and ACT_GE_BYTEARRAY . In my process i have a call activity where i am calling another bpmn and passing the " customer" json vairable in the “in Mapping” of the variable tab of call activity and marking it as “Local” .

Issue :- i checked the ACT_RU_VARIABLES for the new process instance that was called using the “CallActivity” and i see that the “Customer” is created with “type_” as “null” instead of “json” and also i do not see the customer data in ACT_GE_BYTEARRAY .
