API error no parameters when there are parameters given - php

Question

This is the error I'm getting, as you can see there is a parameter in the URL, but the error says there weren't any parameters given. Can anbody help me out?
Client error: PUT https://webapi.teamviewer.com/api/v1/devices/d38237721?alias=laptop-test resulted in a 400 Bad Request response:
{"error":"invalid_request","error_description":"no parameters were given.","error_code":1}
This is my code
public function update($device_id, $options)
{
$token = 'thereisatokenhere';
$client = new Client(['base_uri' => 'https://webapi.teamviewer.com/api/v1/']);
$headers = [
'Authorization' => 'Bearer ' . $token,
'Accept-Language' => 'en-US',
'Content-Type' => 'application/json'
];
$response = $client->request('PUT', 'devices/' . $options['device_id'], [
'headers' => $headers,
'form_params' => [
'alias' => $options['alias'],
],
]);
$response = json_decode($response->getBody()->getContents(), true);
$deviceIdsAPI = $response['devices'];
return $deviceIdsAPI;
}
2nd
$request = new Request('PUT', 'https://webapi.teamviewer.com/api/v1/devices/' . $options['device_id'], ['alias' => $options['alias']]);
$response = $client->send($request, ['timeout' => 2, 'headers' => $headers]);

Answer 1

Here is an example of a PUT request in Guzzle:
$client->put('devices/' . $options['device_id'], [
'body' => [
'alias' => $options['alias'],
'other_field' => '123'
],
'headers' => $headers,
'allow_redirects' => false,
'timeout' => 5
]);
Update:
In the latest version (Guzzle 6) it should be like this:
use GuzzleHttp\Psr7\Request;
$request = new Request('PUT', 'http://httpbin.org/put', ['test' => '123']);
$response = $client->send($request, ['timeout' => 2, 'headers' => $headers]);
See this answer and here is the official Guzzle documentation
