`cast.show_lovelace_view` appears to strip out query parameters from `view_path`

[felipecrs]

The problem

I want to do the following:

service: cast.show_lovelace_view
data:
  view_path: "0?frigate-card-action:camera_select=portao"
  dashboard_path: frigate-card
  entity_id: media_player.tv_da_sala

I.e. pass a query parameter to the view_path, so that the casted page should be:

https://<my-hass>/frigate-card/0?frigate-card-action:camera_select=portao

However, apparently the query parameters are stripped out before being sent to the media player. The casted lovelace view behaves as if there was no query param at all.

FYI on my side query params seems not to be striped out but the dashboard view is not found :

Here is how I call the cast.show_lovelace_view service :

service: cast.show_lovelace_view
data:
  entity_id: media_player.kitchen_google_home
  dashboard_path: frigate-cameras
  view_path: default_view?frigate-card-action:camera_select=camera.garden_patio

And it's the same problem with media_player.play_media service :

service: media_player.play_media
data:
  entity_id: media_player.kitchen_google_home
  media_content_type: lovelace
  media_content_id: "frigate-cameras/default_view?frigate-card-action:camera_select=camera.garden_patio"

Note if I remove the ?frigate-card-action:camera_select=camera.garden_patio part, it works with both services.

@Neonox31 have you tried with 0 instead of default_view?

[Neonox31]

@felipecrs Indeed, it seems to work using 0 instead of default_view, thanks a lot ! But I don't understand why !

But camera selection doesn't occur, so I'm not sure that query params are correctly taken account using 0 😥
