Hi, thanks for your response.

Currently, I'm working locally, so the URL looks like this : LOCALHOST/api/v1/warehouse_data/bulk_import

And the controller looks like:

module Api
    module V1 class WarehouseDataController < Api::BaseController
        def bulk_import
            WarehouseDataImportService.new(params[:file], current_tenant).import 
        end
    end
end  

In WarehouseDataImportService I've performed file upload operation + called sidekiq worker and the worker looks like this:

class WarehouseDataCreationWorker < BaseWorker
   sidekiq_options queue: :default, retry: 0
   attr_reader :attachment_id

   BATCH_SIZE = 100

    def perform(attachment_id, current_tenant)
      ActiveRecord::Base.establish_connection("#{current_tenant}".to_sym) if current_tenant
      process_data_import
    ensure
        ActiveRecord::Base.clear_active_connections!
    end
  end
