undefined method `env' for nil:NilClass after Rails upgrade 4.2.8 from 4.0.1
I recently upgraded rails from 4.0.1 to 4.2.8. After upgrading I am getting below issue. I tried to resolve by upgrading devise gem but it didn't help.
undefined method `env' for nil:NilClass
Solution
Per this issue peek 1.1.0 introduced some changes that work with rails 5.
It looks like peek 1.0.1, https://github.com/peek/peek/blob/v1.0.1/lib/peek/railtie.rb, does not have that change so, locking peek to 1.0.1 should fix the issue .
