Webhook to Home Assistant

[JoshuaSeidel]

Describe the bug
with Frigate 0.16 currently it often does not get a snapshot intime for notification with changes made, i saw frigate-notify put in some logic to help with this change. so i created a webhook with home assistant in a automation to then use the data from frigate notify for the home assistant notification (i dont want to install another app currently). i get this

data:
    __type: <class 'multidict._m
ultidict.MultiDictProxy'>
    repr: <MultiDictProxy()>"

Expected behavior
to get a JSON payload to be able to map data from payload to build a notification

To Reproduce
create a new automation with a webhook as a trigger.
copy the URL for the webhook.
configure frigate-notify webhook to send using defauls

• Frigate NVR: 0.16

Ah, looks like I made a typo in the JSON template when I added the sublabel field (#219) to the template. I think it might be better if I go back and re-work this to avoid using the text template entirely for generating the alert payloads.

Thanks for reporting & I'll have this fixed in the next release

thanks @0x2142 i put in a PR in the meantime so i can use a devbuild while waiting for your next release. #224

@0x2142 now seeing this: orjson.JSONDecodeError: trailing comma is not allowed: line 16 column 79 (char 541)

I was able to work a little last night on the updated webhook notifier - and just merged it into the dev branch. Can you try again with the new image?

Also, just out of curiosity - Have you tried playing around with the max_snap_retry config setting I added in 0.4.3? For my instance, I've actually adjusted up to waiting a full 60 seconds for snapshots.. and even then still some aren't ready in time. Just wondering what other people have seen, and if you've had any luck with extending the time.

[JoshuaSeidel]

@0x2142 i went and just upgraded. i upped mine to 60 now to see. i also made it in the home assistant automation that it takes the ID from the webhook and puts it in the home assistant frigate integration api. so it will load pictures. i want to next figure out the if statements to have it change the way its notifying if there is a sub-label of a license plate, or person identified. but that will take some manual yaml. but your solution as a middle man fixes the issue with 0.16 taking longer to produce a snapshot with whatever they changed. so now it will wait for the snapshot and give me a clean notification.

i'll report back later to see if i get anymore , errors

@0x2142 works great! just wish i could merge this in with HA_Blueprints automation and life would be perfect lol
