Deploy Ruby on Rails app with railway.app

I'm trying to deploy my app on railway.app with Redis (using Sidekiq).I'm using buildpacks and the problem is I have 2 buildpacks and railway says in its documentation only one buildpack is executed in the Procfile.This is my Procfile:

web: bundle exec puma -C config/puma.rbworker: bundle exec sidekiq

How could I execute both processes?
