How to fix bot startup error on node.js?

Question

In contact with

For the first time I am making a bot for VKontakte. I watched the video guide, did everything exactly, maybe VK changed this method? But when I enter the string that the server should return, the following error appears on startup:
C:\Users\user\Desktop\bot>node bot
C:\Users\user\Desktop\bot\bot.js:9
confirmation: 'cb97c487 '
^^^^^^^^^^^^
