How to set a Map as Value for InputParameter using BPMN Moddle

Hi Phillip,

That worked, I appreciate your help.

Thank you again,

You create an input parameter with a map as follows:

const entry = moddle.create("camunda:Entry", { key: "foo", value: "bar" });

const map = moddle.create("camunda:Map", { entries: [entry] });

entry.$parent = map;

const inputParameter = moddle.create("camunda:InputParameter", {
  definition: map
});

map.$parent = inputParameter;

I do have a follow up question, though.

Your solution works great. How can I access the entry’s value by key on my backend?

I’m using Java/Kotlin:

    import org.camunda.bpm.engine.externaltask.LockedExternalTask

    //... irrelevant code

    val nodeInput = lockedExternalTask.variables.getValue(RunJobConstants.NODE_INPUT) as String
   

I was doing this to get my value from a string, but now, that string is wrapped in a map and an entry.

By the way, where can I find the API reference or somewhere I can check this on my own? I’m having a hard time locating stuff.

Thanks for your help.
