PUT requests with parameters with location of "postField" result in Exception

[tomfotherby]

I'm using v0.5 of this service. I have a Service Description with a operation that uses 'httpMethod' => 'PUT':

$api = new GuzzleHttp\Command\Guzzle\Description([
            'baseUrl' => $myBaseUrl,
            'operations' => [
                'SubscriberChangeEmail' => [
                    'httpMethod' => 'PUT',
                    'uri' => '/myapp/api/subscriber/changeEmail',
                    'responseModel' => 'changeEmailOutput',
                    'parameters' => [
                        'oldEmail' => [
                            'location' => 'postField',
                        ],
                        'newEmail' => [
                            'location' => 'postField',
                        ],
                    ],
                ],
                ...

When I try to consume the API I get an exception due to my use of 'location' => 'postField':

exception 'RuntimeException' with message 'Must be a POST body interface' in /var/www/apisupertasker/vendor/guzzlehttp/guzzle-services/src/RequestLocation/PostFieldLocation.php:23

I tried 'location' => 'putField' but that didn't work. I think this was fixed in a previous incarnation of the code, see guzzle/guzzle#278 (but this is in a different git repo - I'm pretty confused about the versions, please excuse me for that 😕 ).

I have the same problem with Method Patch and location postfield.

I use guzzle 5.0 & service 0.4.*

I will close this issue. If your problem still exist with latest versions of Guzzle and Guzzle Service, feel free to reopen it.
