Heroku error on scala application

Question

Any idea what may cause the following error?

sinan@ThinkPad-X1-Carbon:~/dev/heroku/kumbaraci50$ git push heroku master

I was able to push this app couple of days ago with no problem, however something may have changed on my local with package updates. Is there way to increase verbosity of the logging while deploying the app?

This application uses Scalatra framework 2.3 and scala version 2.11.1 on Java 1.8.0_45.

Answer 1

Check that your LANG config var is not set to "tr_TR.UTF-8". You can confirm this by running:

$ heroku config:unset LANG

Certain LANG values result in certificate errors on Heroku. Instead, you may be able to use -Dfile.encoding by running this:

$ heroku config:set JAVA_OPTS="-Dfile.encoding=tr_TR.UTF-8"

Hope that helps.
