Workflow: how to print Object value ?

[stryker129]

Hello,

I'm in progress with ITOM training: https://developer.servicenow.com/app.do#!/training/article/app_store_learn_orchestration_istanbul_c_...

In workflow I've "Log Message" activity - 'cause I'd like to print ${data} object itself. So JSON.stringify(${data}) doesn't work: system logs say that

Information

JSON.stringify([object com.glideapp.workflow.element.WorkflowDatabus])

So what is the best way to easily "print" object value ?

Thanks in advance

I think you will have to print each property of ${data} individually like ${data.get(3).distance} , ${data.get(3).duration}

JSON.stringify can take in javascript object and converts in JSON string. As ${data} is an object of WorkflowDatabus, so JSON.stringify could not evaluate it to JSON string.

[stryker129]

${data.get(3).distance} , ${data.get(3).duration} are not the cases.

I would like to "debug" and see ALL DATA which comes from response. How can I do that?

Is there any loop through all elements of this JSON object?

Thanks for reply.

You can't stringify a non JavaScript object like com.glideapp.workflow.element.WorkflowDatabus. That is probably a Java object. You would have to use a script activity to create a JavaScript object then iterate through all the properties of the Java object and add them to the JavaScript object. Then you could use JSON.stringify to convert it to a JSON encoded string. Here is a small example using GlideRecord as the source:

var gr = new GlideRecord('incident');

gr.initialize();

var JSobj = {};

for (var prop in gr) {

  try{ JSobj[prop] = String(gr[prop] ); } catch (ex) { gs.log(ex); }

}

var str = JSON.stringify( JSobj );//{'prop1':'Hello','prop2':'World'}

gs.log(str);//server side log

You can try the following code in a Run Script activity:

var maxActivityCount = 100;

for (var i = 0; i < maxActivityCount; i++) {

      try {

              var databus = data.get(i);

              workflow.info("[" + i + "] " + JSON.stringify(databus));

    } catch (err) {

              // workflow.info(err.message);

    }

}
