Describe the bug

I've recently experienced that in redis cluster only, the INCRBY probably parses the key to extract the value to increment from.

To reproduce

127.0.0.1:7002> INCRBY "82160ab973ba9a1a7.74819479:counter" 10
(error) ERR value is not an integer or out of range

Expected behavior

127.0.0.1:6379> INCRBY 82160ab973ba9a1a7.74819479:counter 10
(integer) 10

Additional information

cluster mode only.

Okay, after doing some more research, that is due to the usage of serializers which ensure that the value is actually stored type-safe.
