MeiliSearch::Rails::MSCleanUpJob 404 error when deleting records

[drale2k]

Description
When i delete a record in my rails app which has meilisearch indexing set up, the background job fails with the following error:
Error: MeiliSearch::ApiError: 404 Not Found - MeiliSearch API has not returned any error message. See <no documentation link found>.

Arguments:
[{"index_uid"=>nil, "primary_key"=>"45", "synchronous"=>nil, "_aj_hash_with_indifferent_access"=>true}]

For some reason index_uid is nil and it cannot find the record. My model setup is pretty straight forward

class Episode < ApplicationRecord
  include MeiliSearch::Rails

  ...

  meilisearch enqueue: true do
    attributes :title, :body

    attribute(:categories) { video.categories.pluck(:name) }
    attribute(:published_at) { published_at&.to_i }

    searchable_attributes [ :title, :body ]
    filterable_attributes [ :categories ]
    sortable_attributes [ :created_at ]

    attributes_to_highlight [ "*" ]
    attributes_to_crop [ :description, :transcript ]
    crop_length 50
  end
end

Expected behavior
The document to be deleted from the Meilisearch Index

Current behavior
Error explained above

Screenshots or Logs

Environment (please complete the following information):

• OS: Development ENV on macOS
• Meilisearch server version: Meilisearch Cloud (latest)
• meilisearch-rails version: v0.12.0
• Rails version: v7.1

The error only seems to occur when enqueue is set to true and meilisearch spawns a bg job for the deletion. If i set to enqueue: false it works. This is annoying as i need to queue meilisearch operations to the background to not block the app workers

Thanks for the bug report @drale2k

I believe I found the bug (and I found that I was the one responsible for it 😭 ), could you please try #353 ? Only one line is changed.

@ellnix Thanks a lot for the quick response and fix. I can confirm the PR works
