Persistent instant view issue with a certain comic.

No matter how much I try, I can't get the comic 178983 as instant view. It returns as a normal Telegraph link without the instant view button (mobile version screenshot). It doesn't even show up in the search (by name, author or tag). Here's what I tried ~

fixing the instant view using the 'fix' feature (returns error, see below)
clearing the MongoDB database
shifting to a new database
changing the telegraph access token
changing the bot token / shifting to a new bot
shifting to a completely new hosting instance (both Heroku and Repl.it)

None of them worked. The fixing feature throws this error (not only for this comic) ~

Repl.it :
