REST - Could not find controller on PUT

Question

I'm trying to update a node via REST PUT but failing with the "404 controller not found" error. I have tried everything I know of but still getting the same error.

(No problem on retrieve / index)

Module:

function demoapp_feedback_update($edit, $account, $category) {
  cache_clear_all('demoapp_device_validate_pairing_' . $account->uid, 'cache', TRUE);
  cache_clear_all('demoapp_feedback_load_feedback_article_', 'cache', TRUE);
  cache_clear_all('demoapp_feedback_find_feedback_articles', 'cache', TRUE);
}

function demoapp_services_resources() {
  return array(
 'demoapp_feedback' => array(
  'retrieve' => array(
    'help' => 'Retrieves a feedback article',
    'file' => array('type' => 'inc', 'module' => 'demoapp', 'name' => 'resources/feedback_resource'),

(Inc: nothing to see here)

Resource:

function demoapp_resources_feedback_update_poll($node_id, $chid) {
  global $user;
  global $demoapp_device;

  if (demoapp_validate_not_empty($node_id)) {
    if (!demoapp_validate_not_empty($node_id) || !demoapp_validate_not_empty($chid)) {
  services_error(RESOURCE_ERROR_400_MESSAGE, 400);
    }
  }
  //

  $retrievedVoteID = $chid;

  $node = node_load($node_id);
  $node_wrapper = entity_metadata_wrapper('node', $node);

  $selectedVote = $node_wrapper->poll[$chid]['chvotes'];
  $newVote = (int)$selectedVote + 1;

  $node_wrapper->poll[$chid]['chvotes']->set($newVote);
  $node_wrapper->save();

  watchdog('Poll update', 'Retrieved poll update query', $variables = array(
    'Node id' => $node_id,
    'Node object' => $node,
  ), $severity = WATCHDOG_NOTICE, $link = NULL);

  // Event (POLL_VOTE)
  $event = new demoappEvent();
  $event->type = 'POLL_VOTE';
  $event->name = NULL;
  $event->device_id = ($demoapp_device && $demoapp_device->device_id) ?       $demoapp_device->device_id : NULL;
  $event->user_id = $user->uid;
  $event->registered = time();
  $event->created = time();
  $event_id = demoapp_event_create_event($event);

  if (!$event_id) {
    services_error(RESOURCE_ERROR_500_MESSAGE, 500);
  }
  //

  return array('status' => 'SUCCESS:DONE');
}

function demoapp_resources_feedback_access($op, $args) {

  switch ($op) {
    case 'retrieve':

      break;

    case 'update_poll':
      $access = user_access('access demoapp content');
      break;
  }

  return $access;
}

Output:

Failed to load resource: the server responded with a status of 404 (Not found : Could not find the controller.)

• Services & ops enabled
• Index/retrieve works
• Authenticated
• Permissions set up properly

Thanks for your time.

Edit: JS function

postOpinion: function(data, onProgress, onSuccess, onAbort, onError){
    var httpHeaders = demoapp.auth.getHttpHeaders();

    var params = {
        node_id: data.nodeId,
        chid: data.vote
    };

    console.log('Params: ', params);

    demoapp.feedbackRemote.restClient.call(config.serverURL + '/' + config.serviceEndPoint + '/demoapp_feedback/update_poll', JSON.stringify(params), {requestMethod: 'PUT', requestDataType: 'application/json', httpHeaders: httpHeaders, responseDataType: 'json'},
        function _onProgress() {
            onProgress(demoapp.feedbackRemote.restClient);
        },
        function _onSuccess(result) {
            onSuccess(result.status);
        },
        function _onAbort() {
            onAbort();
        },
        function _onError(error) {
            console.log('Error: ', error);
            console.log('Sent url: ', config.serverURL + '/' + config.serviceEndPoint + '/demoapp_feedback/update_poll', JSON.stringify(params));
            onError(error);
        }
    );
},

PUT method is only work for creating item, but you didn't define create operation in hook_services_resources.

If you want to update node, please use POST method and define post operation instead.

function demoapp_services_resources() {
  return array(
  'demoapp_feedback' => array(
    'create' => array(
      // your custom code
    ),
    'update' => array(
      // your custom code
    ),
  );
}
