Can't install Frigate Proxy with error: Internal Server Error ("layer does not exist")

[przemoch-dev]

Hi,

I just migrated from ha frigate instance to standalone one and would like to install Frigate Proxy add-on.
Unfortunately, I can't install this one because of the following error:

2025-10-20 09:23:22.179 INFO (MainThread) [supervisor.docker.addon] Starting build for ccab4aaf/amd64-addon-frigate-proxy:1.6

I found fixing it may require full reinstall, but maybe there is a better way to fix it that I did not find.

I will appreciate all help.
Thank you!
