There is a problem to cast Lovelace views from the cast function. Only default_view or ‘0’ will work for now.
You can test this when using the following:
data:
entity_id: media_player.nesthub1288
view_path: '0'
I hope Lovelace views can be send through the cast function.
For now when sending other Lovelace view, we see the message Google Cast error - Unable to find a view with path xxxx
