variableScopes can only resolve variable names: null in JBPM7.32

we have a script task in jbpm , and code is below.

Script Task code:

java.lang.String resTmp = (java.lang.String) kcontext.getVariable("Result");
org.json.JSONArray objects = new org.json.JSONArray(resTmp);
org.json.JSONArray finalArray = new org.json.JSONArray();
for (int i = 0; i < objects.length(); i++) {
  org.json.JSONObject  jsonObject = objects.getJSONObject(i);
    if (jsonObject.getString("card_id").equals(card_id)) {
        finalArray.put(jsonObject);
    }
} 
kcontext.setVariable((java.lang.String)FResult, finalArray.toString());

The build is successful but we are seeing the following error while starting the workflow.

variableScopes can only resolve variable names: null

Solution

  • change the last line to:

    kcontext.setVariable("FResult", finalArray.toString());

    The setVariable() method's first parameter is a String, so you have to put the name your variable between double quotes (" ")
