Try this instead, to wrap the key in quotes:

redis-cli keys "pattern" | xargs -I% redis-cli del "%"

This takes each key as a variable, %, and passes it to redis-cli del but wraps it in double quotes in case it contains non-alphanumeric characters (like period,colon,etc.)

Check what redis-cli --raw keys "$xx" is returning: you'll see that error when you call redis-cli del without any arguments.
