App Crashed

[nthnjustice]

I've followed your instructions for this biuldpack multiple times, but upon deploying a Shiny app to Heroku, the app crashes with an H10 error and no descriptive cause. I see it's been a year since this repository has been updated. Do we know if it's still functional?

I can see that the sample app at http://shiny-example-1.herokuapp.com/ is still running. (Though I may have to take that down; Heroku recently changed their free tier policy.)

It's quite possible that Heroku has changed something in their environment that breaks the build.

Can you post the full error?

Thank you for responding! It's important to me that this work gets deployed on Heroku.

Here is the Heroku log after I try viewing the application:

The libreadline errors definitely look like the kind of thing that would break if Heroku changed the environment. The version of R used by the buildpack may have to be recompiled, uploaded to S3, and the buildpack updated to pull that build.

I'm not able to do debug or rebuild this at this time. I suggest you try https://github.com/virtualstaticvoid/heroku-buildpack-r.

Thank you for the guidance. I'll see what I can come up with from that.
