AttributeError: 'DreameVacuumCameraEntity' object has no attribute '_webrtc_provider'

Confirmed as not a core issue home-assistant/core#129532.
"The issue is in the CC not initializing the Camera Entity by calling the parent class init method when defining its own init method."

[Tasshack]

Not calling the parent class init function is very much intentional but I cannot remember the actual reason behind it.

Hi @Tasshack ,
Your comment below referenced issue #779 and in the issue itself, sounds a bit like #779 will not be merged.
Could you please clarify?
Should it be closed, will this update also make it into the next pre-release version?

Thanks a lot for all your efforts and the pre-release version for the new Dreame vacuuums
Cheers, Mel

[taifunk]

To resolve the issue temporarily, I added the missing attributes to the DreameVacuumCameraEntity class in the camera.py file of the integration. Specifically, I added the following lines to the class:

_webrtc_provider = None
_legacy_webrtc_provider = None
_supports_native_sync_webrtc = False
_supports_native_async_webrtc = False

After adding these attributes, the errors stopped appearing in the logs, and the integration started working as expected.

Hi @taifunk,

Thanks a lot, it is working.

[melianor]

_webrtc_provider = None
_legacy_webrtc_provider = None
_supports_native_sync_webrtc = False
_supports_native_async_webrtc = False

Hi @taifunk, thanks that worked nicely.
Maybe this can make it into a future release?

[auanasgheps]

Hi there, can you please tell exactly where I should add those values in the camera.py file?

Thanks, working!

@taifunk since you deserve the credit, you should create a PR to fix this

The problem still persists on the Home Assistant Core 2024.11.3?
