Invalid config Z-stick Gen5 on Mac OS

I have the following setting on my configuration.yaml file:
usb_path: /dev/cu.usbmodem1421

When I run hass --script check_config, it all appears fine, but on the home assistant page it says :

The following components and platforms could not be set up:
Please check your config

Any help will be appreciated, on how to setup the stick in Mac os.

Do you have the USB path indented two spaces?

Also confirm your zwave USB path is correct.

If it still won’t load please post your log contents here.
