Redis CommandError

18 September 2017

DESCRIPTION: When running starting up a rails application that has redis, a redis error appears. This is the fix.

The Error

$ Redis::CommandError: WRONGTYPE Operation against a key holding the wrong kind of value

The Fix

$ redis-cli
$ flushall


I do not know what causes this error, or why this terminal command fixes it. However it is a regularly occurring error in the application that requires this command to make it go away.
