openvr actions are not active

Question

im trying to get the action binding working.

steamvr doesn't seam to recognise the "new input method" in the steamvr console, but all the bindings get loaded correctly but dont get bound, and binding the with the ui still doesn't produce outputs no errors are thrown, and the actions aren't active and just return empty data (all 0)

    {
      "controller_type": "knuckles",

    }
  ],
