[SomashekarB]

Here is code, currently it's not printing   

var number = current.number;

    var rejectNotes = "";

    var short_desc = current.short_description;

    var article_body = current.text;

    var article_link = gs.getProperty('glide.servlet.uri') + "nav_to.do?uri=kb_knowledge.do?sys_id=" + current.sys_id;

   var author;

    var revisor = current.revised_by;

    if (revisor)

        author = revisor.first_name;

    else

        author = current.author.first_name;

   var approval = new GlideRecord("sysapproval_approver");

approval.addQuery("document_id", current.sys_id);

approval.addQuery("state", "rejected");

approval.query();

if (approval.next()) {

    var approvalSysId = approval.sys_id;

}

    var approval_link = gs.getProperty('glide.servlet.uri') + "nav_to.do?uri=sysapproval_approver.do?sys_id=" + approvalSysId;

    var emailContent = {};

    emailContent.templateContent =

        "<div style='font-size:10pt; font-family:verdana;'>" +

        "Dear  "+author+",<br/>" +

        "<br/>" +

        "Knowledge Article: " + number + " has been rejected for publication. Please review the Approver's comments, adjust the article and re-send it for approval.<br/>" +

        "<br/>" +

        "Click here to review the rejected request: <a href='" + approval_link + "'>rejected request</a><br/><br/>" +

        "Short description: " + short_desc + "<br/>" +

        "<br/>" +

        "Article body: " + article_body + "<br/><br/>" +

        "Click here to view the article: <a href='" + article_link + "'>View Article</a><br/><br/>" +

        "<br/>" +

        "Thank you."

@SomashekarB 

current.author might be a reference field, and you're trying to access first_name directly without ensuring it's a valid GlideRecord object.

var number = current.number;
var rejectNotes = "";
var short_desc = current.short_description;
var article_body = current.text;

var article_link = gs.getProperty('glide.servlet.uri') + "nav_to.do?uri=kb_knowledge.do?sys_id=" + current.sys_id;

// Initialize author variable
var author = "Unknown Author"; 

// Retrieve the revisor (if available)
var revisor = current.revised_by;
if (revisor) {
    var userRecord = new GlideRecord("sys_user");
    if (userRecord.get(revisor)) {
        author = userRecord.first_name;
    }
} else if (current.author) {
    var userRecord = new GlideRecord("sys_user");
    if (userRecord.get(current.author)) {
        author = userRecord.first_name;
    }
}

// Retrieve approval link
var approval = new GlideRecord("sysapproval_approver");
approval.addQuery("document_id", current.sys_id);
approval.addQuery("state", "rejected");
approval.query();

var approval_link = "#"; // Default value
if (approval.next()) {
    approval_link = gs.getProperty('glide.servlet.uri') + "nav_to.do?uri=sysapproval_approver.do?sys_id=" + approval.sys_id;
}

// Construct email content
var emailContent = {};
emailContent.templateContent =
    "<div style='font-size:10pt; font-family:verdana;'>" +
    "Dear " + author + ",<br/>" +
    "<br/>" +
    "Knowledge Article: " + number + " has been rejected for publication. Please review the Approver's comments, adjust the article and re-send it for approval.<br/>" +
    "<br/>" +
    "Click here to review the rejected request: <a href='" + approval_link + "'>rejected request</a><br/><br/>" +
    "Short description: " + short_desc + "<br/>" +
    "<br/>" +
    "Article body: " + article_body + "<br/><br/>" +
    "Click here to view the article: <a href='" + article_link + "'>View Article</a><br/><br/>" +
    "<br/>";
