I can't get start a Workflow via Web Script.

I created the file workflow.get.js:

var nodeId = args.nodeid; //fdadc86f-d996-472d-8267-850a63573b02
var workflowName = args.w; //jbpm$wf:adhoc
var document = search.findNode("workspace://SpacesStore/" + nodeId); 
var workflowAction = actions.create("start-workflow"); 
workflowAction.parameters.workflowName = workflowName; 
workflowAction.parameters["bpm:workflowDescription"] = "Please edit: " + document.name; 
workflowAction.parameters["bpm:assignees"] = [people.getPerson("admin"), people.getPerson("admin")];
var futureDate = new Date(); 
futureDate.setDate(futureDate.getDate() + 7); 
workflowAction.parameters["bpm:workflowDueDate"] = futureDate; 
workflowAction.execute(document);

Hi,

ScriptNode findNode(string noderef) 
Returns a single ScriptNode as specified by the string form of the NodeRef for that node, null is returned if the search failed.
‍‍‍‍

So from the error presented it looks like the node reference you are searching for does not exist.

Perhaps you could use the Node Browser in the Explorer client to double check that node reference being passes exists?

Cheers,
Roy
