If you're seeing this error, try heroku ps:scale web=0 then import the database again and run heroku ps:scale web=1 afterwards. Found nothing on google for this error, so posting this gist with the solution that worked for me. Could have been a temporary error too.

More info

Writing this down in case it's useful for someone.

The reason why my oculus had inverted positional tracking (when I lean in, it moved me backwards in the 3d scene) was that my camera cable was broken. Ensure the little blue light is on when using the rift.

What type of app?

A web UI, maybe a phoenix app, or something simpler.

Basic version: list failed jobs, allow you to retry or delete them.

Toniq.failed_jobs Toniq.retry(job) Toniq.delete(job)

For us this turned out to be that we had cached html generated by the rails 3 app that had the ASCII-8BIT encoding, clearing all html caches fixed this.

To arrive at this, we first added this debug code:

# if you reuse this: ensure it matches the method in your version of rails
# as the method is overwritten by this monkeypatch

# config/initializers/debug_encoding_errors.rb
ActiveSupport::SafeBuffer

If you have a body like this:

payload={"data": "5 %"}

Then nginx will most likely give you a 400 bad request error.

To get around this, encode the json with "x-www-urlencoded" encoding.

A web framework like rails will transparently decode "x-www-urlencoded" for you.
