Bulk Migrate Error in 9.1.2

[wavesound]

Hello,

We're getting this error when attempting to bulk migrate error in Proxmox after upgrading to 9.1.2. This seems like a bug that I'm sure we can workaround but I wanted to share it with the Proxmox team since we never saw this before 9.1.2.

did you clear the browser cache? was it the new datacenter bulk migration or the per-node one?

yes also deep clean browser. And bulk migration per node.
Here as attachment, a couple of screenshots

I had to add "max_workers: 1" to /etc/pve/datacenter.cfg to get migration working

Surely it's the most immediate solution, but I have no idea if it could be a problem in the long term. Maybe it's just a bug in the migration script, so it's best to let the developers fix it.
