Exception during REST call: "GlideRestMessage" is not defined.

[appstorm]

I am using a non-client callable Script Include and a script in workflow editor to post data, via REST API.  However, I keep getting this error: [Late Add Script] Exception during REST call: "GlideRestMessage" is not defined.  

Workflow Script

// Access the student_information and course_information reference fields from the current record
var studentInfo = current.variables.student_information;  // Reference to the LARF Banner Student record
var courseInfo = current.variables.course_information;    // Reference to the LARF Banner Courses record

// Initialize variables for student_id, crn, and term_code
var studentId, crn, termCode;

// --- Step 1: Retrieve Student ID using Script Include ---
if (studentInfo) {
    var studentId = new LateAddHelper().getStudentId(studentInfo);  // Call the Script Include to get student ID

    if (studentId) {
        gs.info("[Late Add Script] Successfully retrieved student ID: " + studentId);
    } else {
        gs.error("[Late Add Script] Could not retrieve student ID.");
    }
} else {
    gs.error("[Late Add Script] student_information is not set or invalid.");
}

// --- Step 2: Retrieve CRN and Term Code ---
if (courseInfo) {
    var courseGR = new GlideRecord('sn_uni_req_larf_banner_courses');
    if (courseGR.get(courseInfo)) {
        crn = courseGR.u_crn;
        termCode = courseGR.u_term_code;
        gs.info("[Late Add Script] Retrieved CRN: " + crn + ", Term Code: " + termCode);
    } else {
        gs.error("[Late Add Script] Course record not found for course_information: " + courseInfo);
    }
} else {
    gs.error("[Late Add Script] course_information is not set or invalid.");
}

// --- Step 3: Invoke REST API using the "LARF Banner Student Late-Add" REST Message ---

if (studentId && crn && termCode) {
    try {
        gs.info("[Late Add Script] All required parameters are present. Preparing REST call...");

        // Instantiate the GlideRestMessage object
        var restMessage = new GlideRestMessage();
        
        // Set the REST message by name ("LARF Banner Student Late-Add" as per your configuration)
        restMessage.setRestMessageName('LARF Banner Student Late-Add');
        
        // Set the HTTP method (configured in the REST message; in this case, "Default" -> POST)
        restMessage.setHttpMethod('Default');  // Ensure the method is POST as per the configuration

        // Set the parameters (these are the fields you need to pass to the API)
        restMessage.setStringParameter('student_id', studentId);
        restMessage.setStringParameter('crn', crn);
        restMessage.setStringParameter('term_code', termCode);
        restMessage.setStringParameter('stst_code', 'RE');  // Set status code as 'RE' for late-add

        gs.info("[Late Add Script] Sending REST request with student_id: " + studentId + ", crn: " + crn + ", term_code: " + termCode);

        // Execute the REST message and capture the response
        var response = restMessage.execute();

        // Parse the response
        var responseBody = response.getBody();
        var httpStatus = response.getStatusCode();

        gs.info("[Late Add Script] REST Response Status: " + httpStatus);
        gs.info("[Late Add Script] REST Response Body: " + responseBody);

        // Handle the response status
        if (httpStatus == 200 || httpStatus == 201) {
            gs.info("[Late Add Script] Successfully sent data to Banner for student ID: " + studentId);
        } else {
            gs.error("[Late Add Script] Failed to send data to Banner. HTTP Status: " + httpStatus + ", Body: " + responseBody);
        }

    } catch (e) {
        gs.error("[Late Add Script] Exception during REST call: " + e.message);
    }
} else {
    gs.error("[Late Add Script] Missing one or more required parameters (studentId, crn, termCode). Aborting REST call.");
}

Script Include

var LateAddHelper = Class.create();
LateAddHelper.prototype = {
    initialize: function() {},

    getStudentId: function(studentSysId) {
        if (!studentSysId) {
            gs.error("[Late Add Script] studentSysId is not provided.");
            return null;
        }

        var studentGR = new GlideRecord('sn_uni_req_larf_banner_student');
        if (studentGR.get(studentSysId)) {
            var studentId = studentGR.u_employee_number;
            gs.info("[Late Add Script] Retrieved Student ID: " + studentId);
            return studentId;
        } else {
            gs.error("[Late Add Script] Student record not found for Sys ID: " + studentSysId);
            return null;
        }
    },

    type: 'LateAddHelper'
};

I have also tried using RESTMessageV2 with the same result.

GlideRestMessage is not a valid class

updated workflow script

// Access the student_information and course_information reference fields from the current record
var studentInfo = current.variables.student_information;  // Reference to the LARF Banner Student record
var courseInfo = current.variables.course_information;    // Reference to the LARF Banner Courses record

// Initialize variables for student_id, crn, and term_code
var studentId, crn, termCode;

// --- Step 1: Retrieve Student ID using Script Include ---
if (studentInfo) {
    studentId = new LateAddHelper().getStudentId(studentInfo);  // Call the Script Include to get student ID

    if (studentId) {
        gs.info("[Late Add Script] Successfully retrieved student ID: " + studentId);
    } else {
        gs.error("[Late Add Script] Could not retrieve student ID.");
    }
} else {
    gs.error("[Late Add Script] student_information is not set or invalid.");
}

// --- Step 2: Retrieve CRN and Term Code ---
if (courseInfo) {
    var courseGR = new GlideRecord('sn_uni_req_larf_banner_courses');
    if (courseGR.get(courseInfo)) {
        crn = courseGR.u_crn;
        termCode = courseGR.u_term_code;

    }
} else {
    gs.error("[Late Add Script] course_information is not set or invalid.");

// --- Step 3: Invoke REST API using the "LARF Banner Student Late-Add" REST Message ---
if (studentId && crn && termCode) {
    try {
        gs.info("[Late Add Script] All required parameters are present. Preparing REST call...");

        // Instantiate the RESTMessageV2 object
        var restMessage = new sn_ws.RESTMessageV2('LARF Banner Student Late-Add', 'Default'); // Ensure the method is POST as per the configuration

        // Set the parameters (these are the fields you need to pass to the API)
        restMessage.setStringParameter('student_id', studentId);

        restMessage.setStringParameter('term_code', termCode);

        var httpStatus = response.getStatusCode();

        gs.info("[Late Add Script] REST Response Status: " + httpStatus);
        gs.info("[Late Add Script] REST Response Body: " + responseBody);

        // Handle the response status
        if (httpStatus == 200 || httpStatus == 201) {

    }
} else {
    gs.error("[Late Add Script] Missing one or more required parameters (studentId, crn, termCode). Aborting REST call.");
}

Hello @appstorm ,

Correct syntax to glide Rest Message is as below :

var restMessage = new sn_ws.RESTMessageV2();
