Modify Standard Change Templte - Pre-populate the change request Values

[MR1]

Hi All,

Whenever a user selects the value from the lookup field "Template To Modify,"  populate the Change Request Values fields along with Description and Category.

I tried with a catalog client script on "Modify a Standard Change Template" record producer and a script include, but it's not working. I need help.

-***On change catalog Client script on Template of Modify variable**

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }

    // Add info message for debugging
    g_form.addInfoMessage('Template to modify selected. Fetching data for template: ' + newValue);

    // Call GlideAjax to retrieve the template details from the server
    var ga = new GlideAjax('StandardChangeTemplateUtil');  // Reference to the Script Include
    ga.addParam('sysparm_name', 'getTemplateDetails');     // Function name in Script Include
    ga.addParam('sysparm_template_id', newValue);          // Pass the selected template sys_id
    ga.getXMLAnswer(function(response) {
        if (response) {
            var templateData = JSON.parse(response);

            if (templateData.error) {
                g_form.addErrorMessage(templateData.error);
            } else {
                // Populate fields with the retrieved template data
                g_form.setValue('change_request_values', templateData.change_request_values);  // Change Request values field
                g_form.setValue('short_description', templateData.short_description);  // Other fields as needed
               // g_form.setValue('description', templateData.description);
            }
        } else {
            g_form.addErrorMessage('No data received for the selected template.');
        }
    });
}

Script Include 

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }

    // Add info message for debugging
    g_form.addInfoMessage('Template to modify selected. Fetching data for template: ' + newValue);

    // Call GlideAjax to retrieve the template details from the server
    var ga = new GlideAjax('StandardChangeTemplateUtil');  // Reference to the Script Include
    ga.addParam('sysparm_name', 'getTemplateDetails');     // Function name in Script Include
    ga.addParam('sysparm_template_id', newValue);          // Pass the selected template sys_id
    ga.getXMLAnswer(function(response) {
        if (response) {
            var templateData = JSON.parse(response);

            if (templateData.error) {
                g_form.addErrorMessage(templateData.error);
            } else {
                // Populate fields with the retrieved template data
                g_form.setValue('change_request_values', templateData.change_request_values);  // Change Request values field
                g_form.setValue('short_description', templateData.short_description);  // Other fields as needed
             //   g_form.setValue('description', templateData.description);
            }
        } else {
            g_form.addErrorMessage('No data received for the selected template.');
        }
    });
}
