Heroku\H10 Error\Node.js\ Please, guys help!

[st3p4nb01]

Hello! As in one day I made my bot for the social network VKontakte. Bot did on Node.js on the VK-Promise module.

I downloaded the bot on Heroku by connecting GitHub. At the beginning when I deploy the code, the whole process goes perfectly. All is over, I open the application. For a while everything is fine, I check the bot .. it works. But .. it takes a couple of seconds, and here's the error.

Application error
An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details.

I enter the command line. I enter heroku logs -tail --app <app_name>, of course, I add my application.
And there are many mistakes:
