The bug
I have been using Immich for about 8 months now and thought this was my answer to my Google Photos. However, this weekend I noticed nothing was uploading from my phone. Using AI I did as much troubleshooting as I could. I seem to have an error in the logs: Error in runInIsolateGentle for remote sync. The details are: Null check operator used on a null value. I have done all of the normal stuff like uninstalling the app. When I do that ALL of the pictures come back (so it is able to see the web site), but as soon as it syncs and I attempt to use it (I.e add a picture to the web site, or do an auto back from the phone) it comes up with a generic "Sync Failed. Cannot process backup". However, clicking on the individual files that fail backup and 'upload' works great.

not sure what you need...this just started happening this weekend with nothing changing outside of updating the app.
Additional information
Please help,...again, I thought this might be a solution to replace Google Photos. But without auto uploading I will have to do it all manually...not looking forward to that :(
