Planning a new build from master, or should we put this in the dev branch?

[NickM-27]

I figured it would be good to get it out soon, so master made sense

[mcauwelier]

I'm currently on frigate 0.13.2 and frigate-hass-integration 5.0.1 and I still have these media browser errors for clips and snapshots. By downgrading the frigate-hass-integration to 5.0.0 this is resolved.

[NickM-27]

the error definitely won't be the same given the way that the code changed. It is all using safe access

Below you can find the error for frigate 0.13.2 in combination with frigate-hass-integration 5.0.1:

This seems to be the same as in #600 

[NickM-27]

It's not the same exactly, we can see here that the new code is having this issue because somehow top score doesn't exist in either place which is a separate issue and potentially a backend issue. It would be good to know what the metadata is for this event that is causing the error.

[mcauwelier]

I'm using 'manually' triggered event (https://docs.frigate.video/integrations/api/#post-apieventscamera_namelabelcreate) instead of an event triggered by a motion or an object detection.

perhaps this is the reason why there is no top_score. If you need more info or metadata, could you explain what exactly and where to extract it?
