Template switch: AttributeError: 'str' object has no attribute 'async_render_to_info'

Configuration

I have template switches for my TVs. These have been working for a long time (years). Turning on the TV via the template switch works, but Since 2024.9, when I try to turn off the TV, I get the following error:

AttributeError: 'str' object has no attribute 'async_render_to_info'

I have narrowed it down to the wait_template in my switch definition:

switch:
  - platform: template
    switches:
      bedroom_tv:
        unique_id: 9F8E6127-9825-4667-B3CE-0C6FFC5B2BE2
        value_template: "{{ not is_state('media_player.bedroom_atv', 'standby') }}"
        turn_on:
          service: media_player.turn_on
          target:
            entity_id: media_player.bedroom_atv
        turn_off:
          - service: remote.send_command
            target:
              entity_id: remote.bedroom_atv
            data:
              delay_secs: 2
              command:
                - top_menu
                - top_menu
          - wait_template: "{{ is_state('media_player.bedroom_atv', 'idle' )}}"
            timeout: "00:00:10"
          - service: media_player.turn_off
            target:
              entity_id: media_player.bedroom_atv

If I remove or disable the wait_template, then everything works. As I said, this all worked until 2024.9 (or maybe 2024.9.1 or .2 - I can’t remember which version I updated to from 2024.8.x). For reference, the full error is below:

Check the state history of media_player.bedroom_atv. Is it going unavailable after you issue the turn_off remote commands?

Also I’m not sure if continue_on_timeout: needs to be specified or has a default. It is not mentioned in the docs. Try adding that option.

          - wait_template: "{{ is_state('media_player.bedroom_atv', 'idle' )}}"
            timeout: "00:00:10"
            continue_on_timeout: true # or false if you don't want it to proceed after the timeout.
