Heroku deployment template does not work

I entered all the required fields (PUBLISHER, PUBLISHER_IPI_NAME, PUBLISHER_SOCIETY_PR), but the "Build app" phase failed.

Is it possible to update the template?

Cheers!

EDIT

Ah, nvm, I was missing a part of the stack trace. Seems like my PUBLISHER_SOCIETY_PR isn't valid (I replaced with X)?
