 I am getting the following console error (chrome v63.0.3239.84) on various
 admin pages because of that some buttons on those pages do not respond
 when clicking. I have tested with disabling all the plugins and themes and
 using default theme but still seeing the same error on WP version 4.9.1

  {{{
 Uncaught TypeError: Cannot read property 'action' of null
     at updates.js?ver=4.9.1:2443
     at dispatch (jquery.js?ver=1.12.4:3)
     at r.handle (jquery.js?ver=1.12.4:3)
   }}}
