Problem with Wokflow graph in RTC

The Script is syntactically incorrect. It does not always return a value. Such a Script has to always return a value. Then if this is the script, it is also missing various other parts such as defining WorkItemAttributes.

Hello Ralph @Ralph Schoon

You can refer the whole  below script which i am using .. It was working fine before....But sometime back i found that there was no workflowgraph loaded in Defect WI .Then i switched back to the old process provider then again to the current
Process provider ,Then it started working
But i am unable to find the root cause

dojo.provide("com.example.rtc.js.client.workflow.formal");
dojo.require("com.ibm.team.workitem.api.common.WorkItemAttributes");


(function() {
    var doDebug = true;
    var scriptname = "WorkflowGraph";
    var WorkItemAttributes = com.ibm.team.workitem.api.common.WorkItemAttributes;

    dojo.declare("com.example.rtc.js.client.workflow.formal", null, {

        getValue: function(attribute, workItem, configuration) {
            debug("Start");
           
       
            var workflowType = workItem.getValue(WorkItemAttributes.TYPE);
            debug("workflowType: " + workflowType);
            var workflowState = workItem.getValue(WorkItemAttributes.STATE);
            debug("workflowState: " + workflowState);
           
            //return workflowType + " " + workflowState;
           
            if(workflowType == "defect") {
            return "https://inside-docupedia.bosch.com/confluence/download/attachments/359083805/Defect_0.2.jpg";
           
            }

else if(workflowType == "com.ibm.team.apt.workItemType.story") {
                return "https://inside-docupedia.bosch.com/confluence/download/attachments/359083805/Story_0.2.jpg";
                   
            }
           
           
            return "Workflow type '" + workflowType + "' unknown.";
           
            function debug(display){               
                if(doDebug){
                    console.log(scriptname + " " + display);
                }
            }     
        }
    });
})();

It is impossible, from the script and the description you provide, to answer your question. You may want to contact support. Support can ask for log files etc.

PS: if you return the calculated value into a string or HTML attribute, then I would not expect the link to work or automatically display an image. Automatically displaying an image as explained in https://jazz.net/library/article/1093 at the end of lab 5 only works with attributes of type wiki and the image is attached to a work item as described in said lab, as far as I know.
