Export process job stopped working some versions back - not sure which ?

[vw-kombi]

I run on unraid.
I have the import that imports from my live emby server as part of a backup routine, then export to the backjup emby server.
The import is fine, but the export is not.
I also tried the same on the GUI console command - same error.
Do I need to re-create the backend or something ?

This is the command :
docker exec WatchState console state:export -v -s embybackup

This is the output -

Thanks for reporting the issue. it should be fixed soon, The bug is in a code path that rarely used which is why it was probably never fixed.
The relevant issue is #489
