ApplicationRecord Load getting Mysql Error

[markhermano]

Hello,

I stumbled into another issue here which only occurs again on CI but works locally.
The gem loads the resource for the ApplicationRecord model but doesn't find a DB table associated with it.

The error I get in GitHub actions is:

Here is the test.log from the Github actions artifacts:

Is there a workaround for this issue?

[markhermano]

I found a solution to the issue above by doing the following in log_fail.rb but I'm unsure if this is a better way of doing it.

json_result["records"] =
    (ActiveRecord::Base.descendants - [ApplicationRecord]).each_with_object({}) do |record_class, records|
      records[record_class.to_s] = record_class.limit(100).map(&:attributes)
    rescue StandardError => e
      raise e
    end
