Question

heroku rake db:migrate --trace --app app-name
  !   Internal server error

This was working fine before.

How to diagnose this?

rake db:migrate works fine on my local db. There is no entry in the log. VERSION=xxx did not help either.

Using rake 0.8.7.

Answer 1

Ok heroku support already helped me out!

Here the workaround

“try running the migration from a bash dyno?”

$ heroku run bash

“Then just run your migration command (something like):”

$ bundle exec rake db:migrate --trace

This was a good work around I could migrate my application.

Cheers,
