Suitelet returns Error 206 Partial Content when referenced in an External Form

The 206 partial content error will be returned by a Suitelet called in a Online Customer form if the following settings on the script deployment are not properly set:

Deployed = T
Status = Released
Execute as Role = Administrator
Available Without Login = T

Audience tab:
All Roles = T or pick select roles

Below is a sample Suitelet and Online Form HTML template to test this:

1. Create a Suitelet //To look up for Company name if it matches an existing email address

/*************************************
*The Suitelet function searches for customer records
* that match a supplied email parameter
* and display company name to an online form
*/

function lookupCompanyName(request, response)
{
    if (request.getMethod() === 'GET')
    {
        if (request.getParameter('email') != null)
        {
         var company = '';
            var entityName;    // Result set of query
            var filters = [];     
            filters[0] = new nlobjSearchFilter('email', null, 'is', request.getParameter('email'));
   
   var columns = [];
            // Set columns to return in result set
            columns[0] = new nlobjSearchColumn('entityid');
            columns[1] = new nlobjSearchColumn('companyname');
           
            entityName = nlapiSearchRecord('customer', null, filters, columns); 
           
            if (entityName !== null)
            {
             entityName = entityName[0];
                company = entityName.getValue('companyname');
                nlapiLogExecution('DEBUG', 'Company name1: ', company);                           
            }
            response.write(company);
       }
    }
}

2. Deploy the script and set the following.
Deployed = T
Status = Released
Execute as Admin = T
Available Without Login = T

Audience tab:
All Roles = T or pick select roles

* The External URL of the Suitelet will be used on the Online Form.

3. Create an Online Customer Form. Use Form Type - Custom HTML template (Setup > Marketing > Online Customer Form > New)

< html xmlns="http://www.w3.org/1999/xhtml">

< script type='text/javascript'>
    function createXHR() {
        var xhr;
        try {
            xhr = new ActiveXObject('Msxml2.XMLHTTP');
        } catch (e) {
            try {
                xhr = new ActiveXObject('Microsoft.XMLHTTP');
            } catch (E) {
                xhr = false;
            }
        }

        if (!xhr && typeof XMLHttpRequest != 'undefined') {
            xhr = new XMLHttpRequest;
        }

        return xhr;
    }           

    // Function to check for existing emails.
    function displayCompanyName() {

        var xhr;    // XMLHttpRequest
        var custemail;  // email value from form
        var url;    // URL of XMLHttpRequest
        custemail = document.getElementById('email').value;     
        url  = 'https://forms.netsuite.com/app/site/hosting/scriptlet.nl?script=50&deploy=1&compid=TSTDRV594044&h=c00ecbe7ea8f49739c6a&email=' + custemail;
        xhr = createXHR();
        xhr.onreadystatechange = function() {
            if (xhr.readyState == 4)
   {
    alert("status: "+xhr.status); //alert to check status
                if (xhr.status == 200)
    {
     alert("status: "+xhr.status); //alert to check status     
     document.getElementById('companyname').value = xhr.responseText;
                }  
            }
        }        
        xhr.open("GET", url,true);
        xhr.send(null);
    }
