3.0.14 Error: ERR wrong number of arguments for 'set' command (Redis::CommandError)

[QuintinAdam]

After upgrading to 3.0.14 I receive this error for any of my jobs using unique jobs.

Probably coming from

sidekiq-unique-jobs/lib/sidekiq_unique_jobs/middleware/client/strategies/unique.rb

Line 51 in 057b606

return conn.set(payload_hash, item['at'] ? 2 : 1, nx: true, ex: expires_at)

ruby '2.2.2'

rails (4.1.12)
sidekiq (3.4.2)
sidekiq-unique-jobs (3.0.14)
redis (3.2.1)

Your redis is old, see the readme about that. Is a configuration option to turn back the old way of unique checking.
