Xero Create new Tracking Option - php

Question

I can't seem to get tracking options created, the Category itself is creating fine.
However firstly - I should point out I believe there is a bug in the Xero-API for PHP, when debugging adding an option according to the documentation here the PUT should be
https://api.xero.com/api.xro/2.0/TrackingCategories/{TrackingCategoryID}/Options
However in the php lib it is
https://api.xero.com/api.xro/2.0/TrackingCategories/{TrackingCategoryID}/TrackingOptions
Even when that is resolved, I get no error however not tracking Option is created, any ideas?
$options = ['US', 'UK'];
$title = 'Region';
$trackingCategory = null;
if(!$trackingCategory) {
$trackingCategory = new \XeroPHP\Models\Accounting\TrackingCategory($xero);
$trackingCategory->setName($title);
$trackingCategory->save();
}
try {
foreach($options as $option) {
$to = new \XeroPHP\Models\Accounting\TrackingCategory\TrackingOption($xero);
$to->setName($option);
$trackingCategory->setOption($option);
$trackingCategory->save();
}
} catch(\Exception $e) {
$this->logger()->info($e->getTraceAsString());
$this->logger()->info("TRACKING: ". $e->getMessage());
return false;
}

Answer 1

So this would appear it is a bug as reported here
The source has not been fixed, however the above link resolves the problem for anyone else searching.

Answer 2

Changing TrackingOptions to Options in XeroPHP worked soughta... but I was still getting a different error. Ended up creating the Option manually
Note: $this->_xero_oauth_object is my \XeroPHP\Application\PublicApplication from authentication
// Create the URL object based on an absolute URL
$url = new \XeroPHP\Remote\URL($this->_xero_oauth_object, "https://api.xero.com/api.xro/2.0/TrackingCategories/{TrackCategoryGuid}/Options");
// Pass this to the request as a PUT request
$request = new \XeroPHP\Remote\Request($this->_xero_oauth_object, $url, \XeroPHP\Remote\Request::METHOD_PUT);
// Probably a better way but I just copied and paste the XML from the Xero API docs.
$request->setBody("<Options><Option><Name>My New Option Name</Name></Option></Options>");
// I wrapped this in a try - if it exists, there will be an error as you cant have duplicates.
try {
$request->send();
} catch (Exception $e) {
\Log::warn("Xero error: " . print_r($request->getResponse(), true));
}
// now option is created, new add the option to the tracking category
$tracking = new \XeroPHP\Models\Accounting\TrackingCategory($this->_xero_oauth_object);
$tracking->setTrackingCategoryID('3fceedc7-764e-490a-ac27-25684473af78');
// tracking category name - not sure if I need this
$tracking->setName('Contractor');
// match the option name above
$tracking->setOption('My New Option Name');
