TypeError: stream.pause is not a function

[GiboMac]

Environment:

• Node.js Version: 16.18.0
• Redis Server Version: 6.0.0
• Node Redis Version: 4.3.1
• Platform: Debian 10

We have a Redis managed instance in the IBM Cloud, version 6

I've created in this way the connection:

import { createClient } from "redis";
import l from "../logger.js";

class RedisClientWrapper {
  constructor() {
    this.connectionConfig = {
      url: process.env.REDIS_URL,
      socket: {
        reconnectStrategy: (retries) => {
          l.info(`Redis reconnect ${retries}`);
          if (retries > 3) return new Error("Too many attemps");
          return 0;
        },
      },
    };
    this.client = null;
    this.state = "idle";
  }

  async initalize() {
    try {
      if (process.env.REDIS_URL.includes("appdomain.cloud")) {
        const ca = Buffer.from(process.env.REDIS_CACERT, "base64").toString("utf-8");
        this.connectionConfig.socket = Object.assign({}, this.connectionConfig, {
          tls: true,
          ca: ca,
        });
      }
      this.client = createClient(this.connectionConfig);
    } catch (e) {
      l.error(`Redis create client error ---> ${e}`);
    }
    try {
      await this.client.connect();
      const foo = this.client.get("foo");
      l.info(foo);
    } catch (e) {
      l.error(`Redis connet error ---> ${e.stack}`);
    }
  }
}
export default new RedisClientWrapper();

When i try to any simple operation this error occurs -> TypeError: stream.pause is not a function

This is the stacktrace

What's wrong in my configuration? Some misaligned deps?

I'm actually not too sure, but the client never calls .pause (at least not directly)...
Have you tried running this code in a "clean" app?

@leibale here some additional context:

• The application is running inside a docker container (with the node specified at the beginning of the issue)
• The command used for run the application inside the container is nodemon index.js

I've found that by running a test and run it with node test.js the connection works. So maybe is something related with nodemon? 🤔

[leibale]

Maybe the error is that you don't have an error listener on the client (which makes the process crash and somehow this error shows up)? try to add this.client.on('error', err => l.error('Redis Client Error', err)); after you create the client

[GiboMac]

found it!
misconfiguration for the connection config 😫

@GiboMac if you can elaborate a little bit more that might help the next person that will get this error... thanks :)
