Why am I getting this error When I use async?
My Code:
bot.onText(/\/start/, async msg => { const opts = { parse_mode: 'Markdown' , reply_markup: JSON.stringify({ keyboard: StartKeyboard, resize_keyboard: true, one_time_keyboard: true }) }; await bot.sendMessage(msg.chat.id, 'Hi', opts); }); Error:
bot.onText(/\/start/, async msg => { ^^^^^ SyntaxError: missing ) after argument list I'm using node.js v6.11.0 with "dependencies":
{ "babel-polyfill": "^6.23.0", "cheerio": "^1.0.0-rc.2", "dotenv": "^4.0.0", "firebase": "^4.1.2", "firebase-admin": "^5.0.0", "node-telegram-bot-api": "^0.27.1", "request": "^2.81.0" },

The "SyntaxError: missing ) after argument list" occurs when we make a syntax error when calling a function, e.g. forget to separate its arguments with a comma. To solve the error make sure to correct any syntax errors in the arguments list of the function invocation.
The JavaScript exception "missing ) after argument list" occurs when there is an error with how a function is called. This might be a typo, a missing operator, or an unescaped string.
Your version of NodeJS (6.11 LTS) is too old and does not support the async/await features. The syntax error is a result of the Javascript interpreter not recognizing the async token and getting confused about arguments.
Upgrade to NodeJS 7.6 or later. https://www.infoq.com/news/2017/02/node-76-async-await
In prior versions, the only way to perform asynchronous behaviour is to use promises.
