When specifying multiple queues as one string, ie: ```yaml development: workers: - queues: real_time,background ``` this does not work. The workers are not taking scheduled jobs (real_time or background) at all. It works for me, when queues are an array, ie: ```yaml development: workers: - queues: - real_time - background ``` Should the documentation be fixed to list queues as array in YAML or maybe the logic to fix comma separated string?
