plugin not working for Ghost 2.13.1

[lokiyxy]

Hi, I'm having a new ghost and nodebb hosting separately on aws ec2.
I have followed all the steps and i found out that
'{{../post.id}}'
need to be changed to
{{id}}
otherwise we will not be able to get articleID.

However, after fixing this, i start to get an error message of ""error":"Unable to post topic"
from library.js line 196
else { res.json({error: "Unable to post topic", result: result}); }

in the Chrome console, there is warning of "Resource interpreted as Document but transferred with MIME type application/json: "http://0.0.0.0:4567/comments/publish"."

really need help to fix this issue, after days of research, there is no resources on the latest ghost
