Deploy to Heroku fails

[Hextar]

Issue

• It's not possible to deploy that repository to Heroku.

How to replicate:

• follow that heroku deploy link as described in this article.
• insert app nam, region and Cloudify api keys
• deploy app
• after some time the deploy will fail

I can share my Heroku logs:

       Love,
       Heroku
       
 !     Push rejected, failed to compile Node.js app.

 !     Push failed

For what I've understood this error is related on node_sass being incompatible with node 16 (latest) but I can't get if the failing deploy is Heroku fault, or something need to be changed on this repository to make it work.

error: ‘remove_cv_t’ is not a member of ‘std’; did you mean ‘remove_cv’

Anyway I will appreciate if I could get some assistance on that!
