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

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 :sob: ), 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
