const ngrok = require("./get_public_url");
const ViberBot = require("viber-bot").Bot;

// Creating the bot with access token, name and avatar
const bot = new ViberBot({
  authToken: "token",
  name: "EchoBot",
  avatar: "url",
});

const http = require("http");
const port = process.env.PORT || 8080;
return ngrok.getPublicUrl().then((publicUrl) => {
  console.log('Set the new webhook to"', publicUrl);
  http
    .createServer(bot.middleware())
    .listen(port, () => bot.setWebhook(publicUrl));
});

Вам нужно поймать отказ от обещания, чтобы понять, что не так:

return ngrok.getPublicUrl().then((publicUrl) => {
  console.log('Set the new webhook to"', publicUrl);
  http
    .createServer(bot.middleware())
    .listen(port, () => bot.setWebhook(publicUrl));
}).catch(e => console.error(e));
