Flood IO - Selenium Script - Unable to run sample Selenium Script in Intelij keep getting For input String Null

Question

I am trying to run the selenium webdriver sample script from flood.io in my local Intelij. But I keep getting an error:

For input String: "null".

I want to be able to run this and then change the code and upload it to flood.io so I can run the load test with my functional selenium test there.

Any help with this?

Error log:

These are only applicable when running on Flood - you will need to provide the Host and Port of your local Selenium WebDriver instance to test locally. you could even use instead of remote driver the following to run on your local:

WebDriver driver;

System.setProperty("PATH-TO-YOUR-CHROMEDRIVER");
driver = new ChromeDriver();
