[BUG] Error and never sending MQTT message when face gets matched - "TypeError: MQTT: recognize error: Cannot read properties of undefined"

[user45876]

Thanks a lot for your great work and taking up the ball :)

Describe the bug
After uploading a known face, it gets matched correctly. However after that, an error message is created and the MQTT message never seems to get sent:

Getting error:
error: TypeError: MQTT: recognize error: Cannot read properties of undefined (reading 'DEVICE_TRACKER_TIMEOUT')

Also the MQTT Topic does not get generated, alas this is expected, as it does not ever seem to send the MQTT message.

Version of Double Take
v1.13.11.6.1 from 12th of november 2023

Expected behavior
After manually uploading a trained picture / known face via the UI, in case it gets recognised, an MQTT message is sent to the MQTT broker (and in this case a sensor in HA is created).

Screenshots

Hardware

• Architecture or platform: [amd64]
• OS: [Home Assistant OS - Linux]

Additional context
Detection is working well so far when manually uploading trained faces. Training is working well.

Please see config (took out comments here for clarity only):

Also, there is an old issue with the original double-take, but I found nothing there that would help me: jakowenko#169

try to add

frigate:
  device_tracker_timeout: 30

into config

Thanks a lot for the hint, that helped. Now the usecase of manually uploading is working so far :)
Without the frigate url set (I am not using frigate but BlueIris), the double-take icon stays red - is that a problem?

Do you have any plans to support additional NVRs like BlueIris? I would be happy to test. It can communicate via MQTT as well (and indeed does here).

it's commercial NVR. I don't plan to support NVRs have only commercial licenses without open-source edition

[user45876]

OK, understood. Is there a planned way to use it without frigate? It would be great to have it automatically process images, when they are put into a directory - maybe I missed that, sorry, if so.

Regarding BlueIris, I just want to say that it is very, very, very reasonable priced and there is nothing else out there which is as good for small / medium home use, IMO. When I started with this, I tried several solutions (including frigate, but I had the wrong hardware, back then) and I am using it since many years. I am very glad that Ken is keeping it up. He is basically a one man show, AFAIK (having no ties or involvement other than being a fan).

Thanks again for your work and your help!

I will make it possible to use Double-Take without Frigate in the next release.

Hi, I am on v1.13.8.1.

I am still getting the above error. Attached are my config and logs.

Is my device_tracker_timeout in the right place under mqtt?

It's because you use it without Frigate
As a workaround, you can add to the configuration

frigate:
  device_tracker_timeout: 30

The problem has already been fixed in the beta version, the fix will be included in release 1.13.11.9
