node-redis: 4.1.0 publish breaks when publishing an integer

This was working fine up until 4.0.6 but starting in version 4.1.0, publishing integers throws the following error.

/node_modules/@redis/client/dist/lib/client/RESP2/encoder.js:20
            throw new TypeError('Invalid argument type');
                  ^

I got the same error. It works for me adding createClient option(legecyMode: true) and connect() together.

import connectRedis from "connect-redis";
...
    const redisClient = createClient({
        legacyMode: true,
    });
   await redisClient.connect();

In this version 4.1.0, Date values are not working anymore too . Before, they worked fine.

I’m not sure if I follow this thoroughly. Publishing integer values has worked for the longest time until 4.1.0. Are we saying that publishing integers is no longer supported?

redisPubClient.publish('channel', 1) used to work but now has to be written as redisPubClient.publish('channel', '1')

please help my production is broken because of this update

@dragonlobster for while, convert to string every value on or before command db.set… when you to execute command get, convert the returned string to correct datatype…
