Fails to Build in Heroku

[ninp0]

This occurs while attempting to Deploy in Heroku. The following are the results of the build log:

-----> Ruby app detected

Please advise. Thanks!

Heroku has stopped supporting Ruby version 2.1.2. There is a goal to bump the version up to a supported Ruby version.

Any update on this ?

We are working on it. The issue is that the datamapper gem is not supported for modern ruby versions so we are working on a significant rewrite internally for those components.

However, we have been able to get docker working for local development and putting the finishing touches on production docker deploys. Hopefully, that should be a good stopgap solution in the meantime.

Hello, has there been any updates on this?

Can you please fix the Deploy to Heroku Button too?

I have reproduced the screenshot below:
