A Minimal Reproducible Example

It is a simple telegram bot with node-telegram-bot-api. I'm using this files:

package.json

{
  "name": "min",
  "version": "1.0.0",
  "scripts": {
    "compile": "npx rimraf dist && tsc",
    "start": "node ./dist/main.js"
  },
  "dependencies": {    
    "dotenv": "^16.0.3",
    "node-telegram-bot-api": "^0.61.0",
    "@walletconnect/sign-client": "^2.17.3",
    "lokijs": "^1.5.12",
    "qrcode": "^1.5.1"
  },
  "devDependencies": {
    "@types/node-telegram-bot-api": "^0.61.4",
    "@types/qrcode": "^1.5.0",
    "rimraf": "^3.0.2",
    "typescript": "^4.9.5"
  }
} 

tsconfig.json

{
  "compilerOptions": {
    "declaration": true,
    "lib": ["ESNext", "dom"],
    "resolveJsonModule": true,
    "experimentalDecorators": false,
    "esModuleInterop": true,

    "strictFunctionTypes": true,
    "strictPropertyInitialization": true,
    "noImplicitThis": true,
    "alwaysStrict": true,
    "noUnusedLocals": false,
    "noUnusedParameters": true,
    "noImplicitReturns": true,
    "noFallthroughCasesInSwitch": true,
    "module": "commonjs",
    "moduleResolution": "node",
    "sourceMap": true,
    "useUnknownInCatchVariables": false,
    "noUncheckedIndexedAccess": true,
    "emitDecoratorMetadata": false,
    "importHelpers": false,

    "outDir": "./dist"
  },
  "include": ["src"],
  "exclude": [
    "./tests","node_modules", "lib", "types"]
} 

.env

TELEGRAM_BOT_TOKEN="Token"
ETH_PROJECT_ID="ID"

and /src folder with two files:

first for bot implemetation

bot.ts

import TelegramBot from 'node-telegram-bot-api';
import * as process from 'process';

const token = process.env.TELEGRAM_BOT_TOKEN!;

export const bot = new TelegramBot(token, { polling: true });

and second for signClient usage with Node.js

main.ts

import dotenv from 'dotenv';
dotenv.config();

import { bot } from './bot';
import QRCode from 'qrcode';
import SignClient from '@walletconnect/sign-client';


bot.on('message', async msg => {
  const chatId = msg.chat.id;
  const projectId = process.env.ETH_PROJECT_ID!;

  const signClient = await SignClient.init({
    projectId,    
    metadata: {
      name: 'Example Dapp',
      description: 'Example Dapp',
      url: '#',
      icons: ['https://walletconnect.com/walletconnect-logo.png']
    }
  });

  try {
    const { uri, approval } = await signClient.connect({
      requiredNamespaces: {
        eip155: {
          methods: [
            'eth_sendTransaction',
            'eth_signTransaction',
            'eth_sign',
            'eth_getTransactionReceipt'
          ],
          chains: ['eip155:84532'],
          events: ['chainChanged', 'accountsChanged']
        }
      }
    });

    if (uri) {
      const image = await QRCode.toBuffer(uri);
      const botMessage = await bot.sendPhoto(chatId, image);

      const session = await approval();

      const [account] = session.namespaces.eip155!.accounts;
      if (account === undefined) {
        bot.deleteMessage(chatId, botMessage.message_id);
        console.log("no account in walletConnect session");
        await bot.sendMessage(chatId, `No account in walletConnect session `);
        return;
      }

      console.log("account: ", account);
    }
  } catch (e) {
    console.error(e)
  }
}); 

I use

npm i
npm run compile
npm run start

Everything is compiling and starting well. I send a message to the bot and it is replying me with the QRcode that I am using with Metamask to connect to BASE Sepolia network. Console is logging my Metamask address and even more, if I send some requests with the connection, they all working well, but not for a long time. Even on this MRE Bot crashes after about 2 minutes of working fine
with ./node_modules/@walletconnect/core/dist/index.cjs.js:1

TypeError: i.terminate is not a function
    at Timeout._onTimeout (/home/gorub/Documents/TONProjects/Novikov/MintBot/min/node_modules/@walletconnect/core/dist/index.cjs.js:1:41151)
    at listOnTimeout (node:internal/timers:594:17)
    at process.processTimers (node:internal/timers:529:7)

Here I provide all the console output

Node.js v22.11.0

The problem is in @walletconnect/core/dist/index.cjs.js in wt/constructor/resetPingTimeout/setTimeout callback()

I am working on Ubuntu, Node.js 22.11.0, not using walletConnectModal.openModal({ uri }) because of using Telegram Bot frontend Opening QRcodes with MetaMask

Expected behavior

Connection must be successfull and must not result the breaking of the all Bot App.
