Problem with Error_controller_spec seemst to be connected with pundit. When we use version 0.3 instead of 1.1 all tests are passing. I have discovered that somehow error record is not correctly assigned in newer verion. Probably we need to look for an issue in spec/factories/error or app/models/error files. Tests are failing at the first step, when creating error -> @error = Error.new(params). Still hasn't solved but im quite close

spec/factories/error.rb
