Question

I have a bizzare error and i do not seem to find any way to fix it. Basically my heroku deployment fails with that message.

i tried a lot of stuff, cleaning assets, precompiling, tmp clear, updating gems, running gem pristine, nothing seems to work.

it was working fine yesterday - and today i was no way near touching the gemfile or omniauth

Any help appreciated.

Answer 1

Turns out hashie gem version 3.5.2 and omniauth-oauth2 1.3.1 do not mix well.

Reverted back to hashie gem 3.4.4 and works.

Answer 2

Version 3.5.3+ of Hashie will solve the problem for you now. We added some logging to the gem to help people that were getting unexpected behavior from setting keys with names that collided with built-in methods in Hash. That logging caused a bunch of issues in OmniAuth and the Elasticsearch gems. Those problems have all been fixed and we have good test coverage for integrations with OmniAuth and will be adding tests for Elasticsearch as well.

Apologies for the problems. Please let us know at https://github.com/intridea/hashie/issues if any more problems occur!
