Show page returns error

[PragmaticEd]

Clicking on error link goes to show page, that returns error.

I followed the tutorial:

1. gem 'errdo'
2. bundle install
3. rails generate errdo:install
4. rails generate errdo ErrorReporting
5. mount Errdo::Engine => "/errdo"

Rails: 5.1.0
Gem: 0.12.14
ruby: 2.5.1

When i replicated the error this is the console's log:

Completed 500 Internal Server Error in 82ms (ActiveRecord: 8.2ms) ActionView::Template::Error (undefined method created_at' for nil:NilClass):
20:
21: div
22: b Oldest
23: = @error.oldest_occurrence.created_at.in_time_zone("EST").to_s(:time_in_zone)
24: div
25: b Newest
26: = @error.newest_occurrence.created_at.in_time_zone("EST").to_s(:time_in_zone)

I think it is something related to the storage of occurrences because when the errors are saved no occurrence is assigned and this is what causes this error
