Good day,
- So I create an output variable using a script with a default
- The variable is a list, empty, but I have tried both empty and a single element
- I have tries both defining it as an empty “List” in the modeler and through this script.
- When I try to consume, the variable I get a deserialisation error
- I use this method elsewhere to good effect, the only difference is here I definitions are solely in scripts.
- I also notice the type of the variable is:
“com.oracle.truffle.polyglot.PolyglotMap<java.lang.Object,java.lang.Object>”
This is the log error for it:
