This is an odd one!
When I freshly import multiple items the sidecar works a treat
But when I place it in a file on it's own and try to import solely the sidecar (metadata change at the last minute) I get this error!
All the articles have that spinny thing that looks like they're doing something for a split second then this happens
It is a local folio - could that be the reason why?
