[mperham]

Which Redis service provider are you using?

[mperham]

It looks like your Redis does not allow/provide the CLIENT SETNAME command.

[mperham]

If you use master, you can now add a nil :id attribute to disable the use of CLIENT SETNAME.

config.redis = { :id => nil }

[vassilevsky]

If the renamed CLIENT command is known, you can remap it:

[RicottaZhang]

I confirm this error is caused by the redis provider, after update the redis provider's redis version, sidekiq 5.0.3 works fine now.

[luizkowalski]

I'm still seeing this error, even though just upgraded Redis to 4.0.1 and Sidekiq 5.0.4

[mperham]

@luizkowalski Put this in your Gemfile and run bundle up redis:

gem "redis", "3.3.3"

[luizkowalski]

Just upgrade redis didn't worked but add redis-namespace fixed

thanks @mperham
