Is the code you show above a copy-paste of what you did run?

I suspect you did run a copy-paste of the Quickstart code from readme.md.
That has a typo in it, it uses hl (for Husky Lens) in the definition, and then h1 (digit "one" instead of char L).

Then i guess, in the issue here, you typed a "corrected" version (h1 works too, but it was meant to be hl).
So, the code above should work.
