TypeError: fetch failed with code ETIMEDOUT

[LESS24H]

Hello,

First of all, don't be hesitate to ask a question if confuse about my question.

So, i was making Tele BOT using REST API. But, when i trigger my REST API using postman, the result is in below :

TypeError: fetch failed
    at node:internal/deps/undici/undici:13185:13
    at process.processTicksAndRejections (node:internal/process/task_queues:105:5)
    at async exports.sendMessage (/root/LESS24H-Digiflazz/controller/tele/sendMessageController.js:25:21) {
  [cause]: AggregateError [ETIMEDOUT]: 
      at internalConnectMultiple (node:net:1122:18)
      at internalConnectMultiple (node:net:1190:5)
      at Timeout.internalConnectMultipleTimeout (node:net:1716:5)
      at listOnTimeout (node:internal/timers:596:11)
      at process.processTimers (node:internal/timers:529:7) {
    code: 'ETIMEDOUT',
    [errors]: [ [Error], [Error] ]
  }
}

This is my code:

const dotenv = require("dotenv");

dotenv.config();

exports.sendMessage = async (req, res) => {
  const { message } = req.body;

  if (!req.body || Object.keys(req.body).length === 0) {
    return res.status(400).json({
      status: 400,
      message: "Bad request",
    });
  }

  try {
    const teleUrl = process.env.TELE_API_URL;
    const teleToken = process.env.TELE_TOKEN;
    const teleChannelId = process.env.TELE_CHANNEL_ID;

    const request = await fetch(
      `${teleUrl}/bot${teleToken}/sendMessage`,
      {
        method: "POST",
        headers: {
          "Content-Type": "application/json",
        },
        body: JSON.stringify(
          {
            chat_id: teleChannelId,
            text: message,
          },
          { family: 4 }
        ),
      }
    );

    res.status(200).json({ status: 200, message: "Success", data: request });
  } catch (error) {
    console.error(error);
    res.status(500).json({ status: 500, message: "Internal server error" });
  }
};

All the request like Message, Token, Channel ID and ect is nothing wrong because working on local. And also i already setting the VPC Network, Firewall Rule with this configuration :

• Direction: Egress
• Action on Match: Allow
• Destination Filters: 0.0.0.0/0
• Protocols and Ports: 443/tcp

I already do this method, but still came with same result. I think something missing, can you tell me?

Thank you

Hi @LESS24H,

Welcome to Google Cloud Community!

It seems you need to add an "Allow Ingress" firewall rule, including the correct ports and protocols. During creation, ensure the rule has a higher priority than other rules. This will ensure that lower priority firewall rules don't affect this setting. Additionally, check if any "Deny firewall rules" could impact your traffic.

For more best practices regarding setting the firewall rules, you may refer to this documentation.

Hope this helps!
