Tests fail only on github actions with rails, elasticsearch and searchkick

Question

Ruby 3.0.3 Rails 7.0.0.alpha2 elasticsearch 7.17.1 searchkick 5.0.3

My tests are all passing on local but not on GitHub action and I don't know why... Do you know how to show the details of the error 500? This is a Capybara test

This is the config that I added

The results

Edit with answers

So I used the rescue_from option from the answer The error was

#<Searchkick::ImportError: {"type"=>"index_not_found_exception", "reason"=>"no such index [companies_test]", "resource.type"=>"index_expression", "resource.id"=>"companies_test", "index_uuid"=>"_na_", "index"=>"companies_test"} on item with id '650928[31](https://github.com/Hubflo-sas/hubflo/runs/5795678731?check_suite_focus=true#step:16:31)2'>

I had to run this command before running the tests bundle exec rake searchkick:reindex:all

Answer 1

<500: Internal Server Error> indicates that some exception has been raised in your controller that wasn't properly rescued. If you can't reproduce the issue on your development environment you can:

1. Either add a begin..rescue in your controller's action, then inside the rescue do: p $ERROR_INFO.message ( $ERROR_INFO is a special variable that contains the last exception rescued, it's a more readable way to use $!

def my_controller_action
  # ... (business logic)
rescue
 p $ERROR_INFO.message
end

you can also add a global rescue_from in you ApplicationController

class ApplicationController
  rescue_from Exception, with: :my_exception_handler

private
  def my_exception_handler
    # exception handling logic ( logging to Sentry for example etc.)
  end
end

and here is a more detailed example from the rails documentation

2. Or, with rails minitest, you can run rails test --backtrace (source here), there are more interesting options in there that you might want to use in your CI, or even when developing locally.
