OCI architecture execution mismatch in Incus cluster

I have a bare metal, dual architecture, Incus 6.8 cluster created by Incus-Deploy. Execution of an OCI image works great, for a single architecture. Second architecture fails:

incus launch docker:hello-world --console --ephemeral
Launching the instance
Error: Failed instance creation: Failed creating instance record: Requested architecture isn't supported by this host
incus image list

Adding a separate remote does not seem to work either.

Does using --target to aim at a specific server help?

It does not.

incus launch --target fortis docker:hello-world --console --ephemeral
Launching the instance
Error: Failed instance creation: Failed creating instance record: Requested architecture isn't supported by this host

Can you show the request with --debug?

incus launch --debug --target fortis docker:hello-world --console --ephemeral
