Issue with the email script

[Prithvi Ramesh1]

Business rule - 

(function executeRule(current, previous /*null when async*/ ) {

    var fields = current.getFields();
    for (var i = 0; i < fields.size(); i++) {
        var field = fields.get(i);
        if (field.changes()) {
            var name = field.getName();
            var fieldLabel = field.getLabel(); // Get the field's label
            var prev = previous.getDisplayValue(name); // Get the previous value of the field
            var value = field.getElementValue(name); // Returns the unformatted value of the element
            var disValue = field.getDisplayValue();
            gs.addInfoMessage('Field Name: ' + fieldLabel + 
                              ' | Previous Value: ' + prev + 
                              ' | Current Value: ' + disValue);
            gs.eventQueue("field.changes", current, prev, disValue);
        }
    }
})(current, previous);

Notifications - 

Notification Email script - 

(function runMailScript(current, template, email, email_action, event) {
    // Add your code here
    var fields = current.getFields();
    var fieldLabel = ""; // Initialize fieldLabel variable
    for (var i = 0; i < fields.size(); i++) {
        var field = fields.get(i);
        if (field.changes()) {
            fieldLabel = field.getLabel(); // Get the field's label
            break; // Exit loop after finding the changed field
        }
    }
    
    var emailBody = "Hello,\n\n" +
                    "This is to inform you that the value of the field " + fieldLabel + " has changed.\n\n" +
                    "Previous Value: " + event.parm1 + "\n" +
                    "New Value: " + event.parm2 + "\n\n" +
                    "Please review the changes at your earliest convenience.\n\n" +
                    "Best regards,\n" +
                    "[Your Company Name]";
    
    template.print(emailBody);
})(current, template, email, email_action, event);

 Name - field_value_changed

When the notification is triggered, then the body returns as empty.

Hello @Prithvi Ramesh1 ,

The correct syntax for including your Email Script would be:

${mail_script:field_value_changed}
