Service camera.snapshot fails after 0.115 upgrade

1

Guys my HA won’t now pull a camera.snapshot from any of my three IP cameras. Two are using the generic platform and one the Amrcest platform. All worked fine on HA 0.114.

Tried using the developer tools to hand launch a snapshot but it ‘fails to call service’ with ‘camera undefined’ as the error type.
My cameras still have the same names as they did before and I can view their picture cards as normal.
Any clues ? Did service call syntax get changed in 0.115 ?

The above exception was the direct cause of the following exception:

Additionally, I’ve updated to 0.115.1 and also done a full power cycle. Problem remains…

I’ve spent a few hours trying to see why this broke for me after 0.115.
I still don’t know why, but I found a workaround.

To make my old automations with camera.snapshot service calls work I have had to ditch the templates with entity_id. and direct specify the filename:

This fails (but worked for me for fine with 0.114)

data:
  filename: '/share/ipcamera/snapshot_{{ entity_id.entity_id }}.jpg'
entity_id: camera.dahua_camera
service: camera.snapshot

This works in 0.115

service: camera.snapshot
data:
  filename: /share/ipcamera/snapshot_dahua_camera.jpg
entity_id: camera.dahua_camera

Thanks for this! I now use this workaround with ffmpeg: instead of the generic IP camera so that I don’t get the entity_id error.
