Lovelace dashboard navigation

For some reason I cannot navigate to alternate dashboards. I have used the navigate service with the navigation target set to /lovelace-newdashboard/0 but depending on various file path variations, I never get the correct dashbiard to display.
Partial code follows:

   - type: grid
        columns: 3
        square: false
        cards:
          - type: custom:button-card
            entity: input_button.hw_reset_button
            name: Boost
            tap_action:
              action: call-service
              service: script.turn_on
              data:
                entity_id: script.hw_temp_boost
            hold_action:
              action: navigate
              navigation_path: /lovelace-hw_detail/0
