Discussion posts and replies are publicly visible
Use key value pair whenever calling any interface or rules from interface. It seems you've called a rule or function inside the interface & its showing error due to missing parameter while calling that . Please check whether any mandatory parameter is missing inside the interface.
what is key value pair?
key value pair means suppose you are calling a rule getdetails it has 3 rule inputs x,y&z , you should call it likerule!getDetails( x: "value" , y : "value" , z : "value")
value can be anything local or ri! or any literal values
wierd, the only rule i use doesn't have any parameters,
my a!startprocess was successfully transmit all datas into processmodel, then what it pinpoint to report this error?
