Error migrating container from LXD to Incus

I’m trying to migrate an instance, via exporting, from LXD 5.0.2 to IncusOS.

environment:
  hostname: 0a6b8533-8f41-6f87-2ad1-48210b51cf30
  machine_id: c9423921293a40518d4a2ed2c4340fd5
  os_name: IncusOS
  os_version: '202608290126'
  os_version_alternate: '202608072311'
  os_version_next: '202608290126'
  system_is_ready: true
  uptime: 1525991

Exporting works correctly but when I try to import on the other side I’m having an error about backup.yaml, which happens if i export with or without --instance-only:

lxc export kingston-nuc:ca-multisite-test1 --instance-only
incus import ca-multisite-test1.tar.gz 
URL: https://.../dex/device?user_code=[code]
Code: [code]

Error: Create instance from backup: Error updating backup file: open /var/lib/incus/storage-pools/local/containers/ca-multisite-test1/backup.yaml: no such file or directory

I can only find this reported twice in the forum, and both related to VMs not containers. I can’t find any related results searching the chats.

Has anyone else encountered this and can suggest a work around?
