That looks like the type of problem that comes up when your program is expecting a newer version of node or the javascript language than what your project is currently using.

The action(() => { syntax is an arrow function, a newer syntax to javascript introduced in ECMAScript 6/2015 spec. It has been supported in Node.js since version 6+

Potential Solution 1: See if you have an old version of node. Run node -v in the command line, confirm that you have a version greater than 6, if you have an old version follow these instructions to install nvm so you can just run a newer version of node for this bot project.

Potential Solution 2: Make sure there is a file here: /var/www/html/bot/.babelrc that contains:

{
"presets": [ "es2015" ]
}

You can check for the file by running ls -a and looking for it.
