I am trying to develop a small rails application. I previously used CarriereWave to store files, but just change to use ActiveStorage. When I save a new record (or destroy a record) , application crash with error message:
Disk Storage (1.4ms) Uploaded file to key: yltgtiwm190dz7kemaj8plz6acpq (checksum: Xjy3wdZBK+KWDKkEgTPVmw==)[ActiveJob] Failed enqueuing ActiveStorage::AnalyzeJob to Sidekiq(default): Redis::CannotConnectError (Error connecting to Redis on 127.0.0.1:6379 (Errno::ECONNREFUSED))Completed 500 Internal Server Error in 373ms (ActiveRecord: 310.0ms | Allocations: 18043)Redis::CannotConnectError (Error connecting to Redis on 127.0.0.1:6379 (Errno::ECONNREFUSED)):However, record is perfectly recorded.
When I start a Redis server, everything work fine, but my question is:
Why does my rails application use Redis, and is it possible to disable it ? (As I use google app engine for production, I do not want to setup Redis server on it).
