Error while calling business process while clicking a call button

Hi Team,

I am trying to call a business process on clicking of active row button(Call). I wrote the below code in section schema page.

Code :

define("UsrCandidates1Section", ["UsrCandidates1SectionResources", "terrasoft", "ControlGridModule",

"BaseProgressBarModule", "css!BaseProgressBarModule", "ProcessModuleUtilities","ProcessModuleUtilitiesResources"],

function(resources, Terrasoft, ProcessModuleUtilities)

{

                "operation": "insert",

                "name": "DataGridActiveRowOpenAction",

                "parentName": "DataGrid",

                "propertyName": "activeRowActions",

                "values": {

                    "className": "Terrasoft.Button",

                    "style": Terrasoft.controls.ButtonEnums.style.BLUE,

                    "caption": "Call",

                    "tag": "Call",

                    "click": {

                        "bindTo": "onOpenPrimaryContactClick"

                    }

                    //Add a new swtich case parameter for the new button added on the active row

                }

            },

  onOpenPrimaryContactClick : function()

            {

                var activeRow =this.get("ActiveRow");

                if (activeRow) {

                        // Determining the base candidate record Id.

                        var primaryId = this.get("GridData").get(activeRow).get("Id");

                        alert(primaryId);

                        if(primaryId)

                        {

                        var args = {

                    // The name of the process that needs to be launched.

                    sysProcessName: "UsrTest",

                    // The object with the ContactParameter incoming parameter value for the CustomProcess process.

                    parameters: {

                        ProcessSchemaParameter1: primaryId

                    },

                    //callback: config.callback,

                    //scope: config.scope

                };

                debugger;

                alert("test1");

                ProcessModuleUtilities.executeProcess(args);

                // Launch of the custom business process.

                alert("test2");

            }

                }

            },

While clicking on the Call Button the alerts which i kept before ProcessModuleUtilities.executeProcess(args) are getting executed.When alert("test1") got executed i am getting the below error.

Can you please let us know where the code went wrong.

hoping for a positive reply.
