Error when migrating VM to different host: Expected array - got scalar value

[nickk]

Hello, I am running Datacentre manager 0.9.2 with two nodes, both on PVE 9.0.17.

I brought all three nodes up to date today and set about trying to migrate a VM from one node to another.



On clicking Migrate the following error is shown:

api error (status = 400: parameter verification errors target-storage: Expected array - got scalar value. target-bridge: Expected array - got scalar value. target-endpoint: property is missing and it is not optional)



To confirm this wasn't a hostA to hostB issue, I tried migrating a different VM from hostB to hostA and received the same error message.

Both VMs in the migration attempt were shutdown/inactive.

Many thanks for any advice.

Same issue here, tried to move ct's from Proxmox Community (9.0.17) to Proxmox Enterprise (9.0.11) host with PDM 0.9.3 Beta.

Same issue here. Trying to migrate multiple VMs from Proxmox Community (8.4.0) to Proxmox Community (9.0.11).

I still have the issue after updating to Datacenter Manager 0.9.4. Tested the migration against Virtual Environment 8.4.14 and 9.1.1.
