Get JS error with custom standard #111

I have tried to create a custom standard, to take only the tests which I need in my project.
As template I use the example inside the resources/sniffers folder.
As far I can see, the creation is successful via a11y-sniffer. But when I use this sniffer I get the error
Test function errored for "http://example.dev/"
I start debugging and find out that I get this JS error when the test is started. Error: HTML CodeSniffer: undefined is not an object (evaluating 'window.HTMLCS.process') .

Can you have a look at this? Maybe some dependencies have been change or something else.
With the original sniffer from the project everything works fine.
