Camera stream error

Home Assistant Configuration details:
Version: Core 2021.5.0
Unifi Protect integration v0.8.7

When trying to stream the doorbell video to my Google Hub, I get the following error:

Triggered manually at May 6, 2021, 4:03:40 PM
Call service camera.play_stream on entities camera.voordeur_deurbel
Stopped because an error was encountered at May 6, 2021, 4:03:40 PM (runtime: 0.01 seconds)
camera.voordeur_deurbel does not support play stream service

This is the automation in which it happens:

alias: Doorbell
description: ''
trigger:
  - type: occupied
    platform: device
    device_id: 68ffc9722xxxxxxxxxxxxxxcd1f7d
    entity_id: binary_sensor.doorbell_voordeur_deurbel
    domain: binary_sensor
condition: []
action:
  - service: camera.play_stream
    data:
      media_player: media_player.hub_b
    target:
      entity_id: camera.voordeur_deurbel
mode: single

How come the standard camera integration does not work?

Here I saw someone who got it working, but unfortunately I seem to get this exact error every time, also with other UniFi Protect camera’s. What could be the problem?
Thanks in advance!
