Why does my app crash after deployment?

Issue

My app crashes after deployment. I have not made any changes to the start-up scripts. My app has heroku/exec buildpack, is it related?

Resolution

If your app meets all the following conditions, it is possible that your app will crash.

• heroku/exec buildpack is set
• HEROKU_EXEC_DEBUG config var is not 1
• There is a bash script located in /.profile.d/ and the script includes set -e command

To avoid the crash , you can choose one of the following:

• Remove -e option from set command
• Remove heroku/exec buildpack
• Set HEROKU_EXEC_DEBUG as 1
