Request error http 400 on <hass>/api/frigate call

[nottledim]

When a notification is sent to android hass app using SgtBatten's notification blueprint it provides the clip url that looks like https://<domain>/api/frigate/notifications/1730296666.946824-qaky68/drive/clip.mp4

Android reports attempting to open this as "this page isn't working" Error 400

Similarly locally or from the browser http://hass:123/api/frigate/notifications/1730296666.946824-qaky68/drive/clip.mp4 returns an http 400 Request Error.

This is using the integration v5.4.0 with frigate 0.14.1-f4f3cfa

Configuration

Frigate is on a separate server from hass

Add your logs here:

I wish I could find something. Frigate integration emits many lines like:
[custom_components.frigate] Finished fetching frigate data in 0.006 seconds (success: True)
and nothing else.  I don't know where else to look.

Incidentally SgtBatten beta version for frigate 0.14 has the same problem. The config is very similar but it has this extra attribute:

video: '{{base_url}}/api/frigate{{client_id}}/notifications/{{id}}/{{camera}}/clip.mp4'

If I set a client_id in that url hass returns 404 error otherwise it returns 400 error.

To me it's like a proxy or remote access problem. My question is what is wrong that provokes the 400 error?

Would be good to see the request details using browser debug tools so we can see what the response is
