Cant submit a gist nor gist-list

Hello,
I'm running gist.el (i think the latest version). When i run M-x gist-list, i get

``
   Using a proxy for https...
   Contacting host: api.github.com:443
   helm-M-x: Wrong type argument: listp, (message . "Not Found") 
   Mark set
``

Is there anything more I can provide? I'm on Emacs 27 on Centos.
Regards
Saptarshi
