You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: uploads_controller.rb
    path of file: ./repos/vets-api/modules/vba_documents/app/controllers/vba_documents/v1
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'zip'
require 'vba_documents/payload_manager'
require '
    
      def show
        submission = VBADocuments::UploadSubmission.find_by(guid: params[:id])

        if submission.nil?
          raise Common::Exceptions::RecordNotFound, params[:id]
        elsif Settings.vba_documents.enable_status_override && request.headers['Status-Override']
          submission.status = request.headers['Status-Override']
          submission.save
        else
          begin
            submission.refresh_status! unless submission.status == 'expired'
          rescue Common::Exceptions::GatewayTimeout, Common::Exceptions::BadGateway => e
            # Rescue and log (but don't raise exception), so that last cached status is returned
            message = "Status refresh failed for submission on #{controller_name}##{action_name}, GUID: #{params[:id]}"
            Rails.logger.warn(message, e)
          end
        end
