when content set to draft WSOD

Hi,

The problem I'm having is when using workbench when saving as draft the URL reverts to the NID which causes the page the WSOD.

I've tried the working with the Action to take if filter value does not validate but that results in the view not displaying at all.

It doesn't seem to like the word, draft at the end of the node path,

this is ok, /node/759153/edit
this is not ok /node/759153/draft

I would have thought using hide view would have been the way to catch the error.
how do I configure this module to allow it to be viewed

this issue is this statement

  if ($result->fetchCol()) {
        $return = TRUE;
      }

this whole section seems unneeded as it isn't assessing the permissions correctly and returning a false value shouldn't result in a WSOD.

elseif (is_numeric($argument)) {
      // Node access isn't technically necessary for a single nid as views
      // permissions would not allow any data exposure.
      // That said, node access gives an expected experience as this validate
      // plugin will return FALSE if they don't have access.
      $result = db_select('node', 'n')
        ->addTag('node_access')
        ->condition('nid', $argument, '=')
        ->countQuery()
        ->execute()
        ->fetchField();

      
      if ($result->fetchCol()) {
        $return = TRUE;
     }
    }

and getting rid of the IF statement and just returning true resolves the issue.
