Background: monitoring a Redis cluster what is filled with jobs by node resque.

It seems the error isn't directly from the library but a complaint from Redis itself. Stack Overflow. It seems like the requested keys (worker ids) requested in the command aren't coming from a single node.

This is the function actually requesting the values. If that is raising this error then it seems the node_for function isn't getting the expected value. The first step would probably be updating the latest version of the redis gem you can if you haven't already.

the same problem persists with redis-4.2.2 gem.
