Rails 6.1's ActiveModel Errors Revamp breaks error response

[KubaSemczuk]

Rails 6.1 changed how ActiveModel errors are structured (explanation, Pull Request). It affects jsonapi_errors_handler error output.
Error that looked like that:

{
  "errors": [
    {
      "status": 422,
      "title": "Invalid request",
      "detail": "can't be blank",
      "source": {
        "pointer": "/data/attributes/magento_id"
      }
    }
  ]
}

now looks like that:

{
  "errors": [
    {
      "status": 422,
      "title": "Invalid request",
      "detail": null,
      "source":{
        "pointer": "/data/attributes/#<ActiveModel::Error:0x00007fcfe9f8b0e0>"
      }
    }
  ]
}

So information what error is about is lost.

@KubaSemczuk Thanks for reporting this! Do you opt for a PR? :)

Hi. I'm not sure I'm ready for it skillwise (meaning I'm afraid it would take me ages and I won't have that much free time in next few weeks). I've never contributed to any gem. But I'll take a look at it on the weekend. Can't say I opt for it for now.

Ok, let me know how it's going!

[KubaSemczuk]

Sorry for not getting back to you. Life got in the way and I forgot. I have to say that I won't have time to take care of that in nearest future.

No worries, added to my todos

im in rails 6 as well and overwriting the serializable_hash method inside JsonapiErrorsHandler::Errors::Invalid worked for me

class JsonapiErrorsHandler::Errors::Invalid
  def serializable_hash
    errors_array = []
    errors.to_h&.each do |error|
      errors_array << {
        status: status,
        title: title,
        detail: "#{error[0]} #{error[1]}",
        source: { pointer: "/data/attributes/#{error[0]}" }
      }
    end

    errors_array
  end
end

now im getting something like this

{
   :errors=>[
      {
         :status=>422,
         :title=>"Invalid request",
         :detail=>"title can't be blank",
         :source=>{
            :pointer=>"/data/attributes/title"
         }
      },
      {
         :status=>422,
         :title=>"Invalid request",
         :detail=>"content can't be blank",
         :source=>"{
            :"pointer=>"/data/attributes/content"
         }
      },
      {
         :status=>422,
         :title=>"Invalid request",
         :detail=>"slug can't be blank",
         :source=>{
            :pointer=>"/data/attributes/slug"
         }
      }
   ]
}
