Getting "ERR syntax error" on set using node-redis

Question

I am unable to set and get key in redis using node-redis. But set and get works well when using redis-cli. This is my code:

const redis = require('redis');
const util = require('util');

const GLOBAL_KEY = 'lambda-test';
const redisOptions = {
    host: process.env.REDIS_HOST,
    port: process.env.REDIS_PORT
}

try{
    test();
}
catch(err) {
    console.log('catch err ' + err);
}

async function test() {
    var client = redis.createClient(redisOptions);
    client.on("error", function(error) {
        console.error(error);
    });
    client.get = util.promisify(client.get);
    client.set = util.promisify(client.set);
    await client.set("ke", "test1", redis.print).catch(function(err){console.log('err: '+ err);});
    await client.get("ke", redis.print).catch(function(err){console.log('err: '+ err);});
}

Output:

err: ReplyError: ERR syntax error
err: ReplyError: ERR wrong number of arguments for 'get' command

Can't figure what the reason is, can anyone help me figure what I am missing?

Update: I tried using bind, but no luck:

    client.get = util.promisify(client.get).bind(client);
    client.set = util.promisify(client.set).bind(client);

Also I have enabled the DEBUG to get extra logs:

Thanks all for suggestion. I posted the question as issue on the repo https://github.com/NodeRedis/node-redis/issues/1599 and got the answer from leibale:

async function test() {
    const client = redis.createClient(redisOptions);
    client.on("error", function(error) {
        console.error(error);
    });
    client.get = util.promisify(client.get).bind(client);
    client.set = util.promisify(client.set).bind(client);

    try {
        console.log('SET reply:', await client.set("ke", "test1"));
    } catch (err) {
        console.error(err);
    }

    try {
        console.log('GET reply:', await client.get("ke"));
    } catch (err) {
        console.error(err);
    } 
}

The issue was bind and use of redis.print as a callback
