Question

I have followed the pandastream setup docs on Heroku, available here https://devcenter.heroku.com/articles/pandastream

However when using heroku run console and executing Panda::Profile.all I get

irb(main):001:0> Panda::Profile.all
NoMethodError: undefined method `connection' for nil:NilClass
    from /app/vendor/bundle/ruby/1.9.1/gems/panda-1.5.0/lib/panda/modules/cloud_connection.rb:4:in `connection'
    from /app/vendor/bundle/ruby/1.9.1/gems/panda-1.5.0/lib/panda/modules/finders.rb:19:in `find_object_by_path'
    from /app/vendor/bundle/ruby/1.9.1/gems/panda-1.5.0/lib/panda/modules/finders.rb:23:in `find_by_path'

    from script/rails:6:in `require'
    from script/rails:6:in `<main>'

Testing it locally works fine with the intended results. Any ideas?

Some sanity checks

1. Did you create the file config/initializers/panda.rb as given in guide for initializer?

2. Run heroku addons:open pandastream & verify your S3 bucket and credentials. a wrong credential will most likely lead to connection error like you are seeing in your stack trace

3. try update to the latest version of typhoeus & panda to see if that helps

Hope it helps. And don’t forget to Post back, if none of this helps.
