Got Invalid argument type error when connect to redis container-CodePudding

I'm playing with docker and redis and I want to start redis from the official docker image:

docker run -p 6379:6379 redis
1:C 02 Oct 2022 08:11:14.410 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
1:C 02 Oct 2022 08:11:14.410 # Redis version=7.0.5, bits=64, commit=00000000, modified=0, pid=1, just started
1:C 02 Oct 2022 08:11:14.410 # Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf
1:M 02 Oct 2022 08:11:14.410 * monotonic clock: POSIX clock_gettime
1:M 02 Oct 2022 08:11:14.411 * Running mode=standalone, port=6379.
1:M 02 Oct 2022 08:11:14.411 # Server initialized
1:M 02 Oct 2022 08:11:14.412 * Ready to accept connections

In my nodejs application I try to connect to the container but it failed and I got this error:

➜  red node app
connect!!! Promise { <pending> }

This is my code:

(async () => {
  const redis = require("redis");
  const client = redis.createClient({
    socket: {
      host: "localhost",
      port: 6379,
    },
    // password: '<password>'
  });

  client.on("error", (err) => {
    console.log("Error "   err);
  });

  await client.connect();

  client.set("bla", true);
  const y = client.get("bla");

  console.log("connect!!!", y);
})();

Why I can't able to connect to redis container?

CodePudding user response：

You can only set strings or numbers:

client.set("bla", true);

should be

client.set("bla", "true");
