onSubmit Catalog Client Script not working for Non-Admin Users

[AnkurBaruah]

I have this working onSubmit Catalog Client Script code. When I try it in ESC portal or Native UI as a system administrator or a user with Admin role, it works fine. But when I try by impersonating as a non-admin user and try to submit a catalog request. It shows it had some error.

Below I have shared the Script:

var isSubmitting = false; // Global flag to track submission status

function onSubmit() {
    if (!g_form.ajaxComplete && !isSubmitting) {
        getData();
        return false;
    }
    return true; // Allow submission if `g_form.ajaxComplete` is true
}

function getData() {
    var groupName = g_form.getValue('group_name');
    var memberCount = g_form.getValue('EU06') ? g_form.getValue('EU06').split(',').length : 0;

    var ga = new GlideAjax('isGroupCreated');
    ga.addParam('sysparm_name', 'isNameExists');
    ga.addParam('Group_Name', groupName);

    // Make an asynchronous call
    ga.getXMLAnswer(function(response) {
        if (response == 'false' || response === false) {
            // If group name exists, show error and prevent submission
            alert('Group with the same name already exists. Please try with a different name.');
            g_form.addErrorMessage('Submission canceled due to duplicate group name.');
        } else if (response == 'true' || response === true) {
            // If name is unique, prompt user for confirmation
            var confirmation = confirm(
                'Please confirm your request details:\n' +
                'Group Name: ' + groupName + '\n' +
                'Description: ' + g_form.getValue('EU02') + '\n' +
                'Group Email: ' + g_form.getValue('EU03') + '\n' +
                'Manager for the group: ' + g_form.getDisplayValue('EU04') + '\n' +
                'Number of Members: ' + memberCount
            );

            if (confirmation) {
                // Set flag to true to indicate submission in progress
                isSubmitting = true;
                g_form.ajaxComplete = true;

                // Submit the form based on the environment
                if (window == null || window === 'NULL') {
                    g_form.submit();
                } else {
                    $j("#oi_order_now_button").trigger('click');
                    $j("#submit_button").trigger('click');
                }
            } else {
                g_form.addErrorMessage('Submission canceled by the user.');
            }
        } else {
            // Handle unexpected errors
            g_form.addErrorMessage('Unexpected error occurred during form submission.');
        }
    });
}
