Problem creating vmware_desktop image with Packer

I’m working on a repo that includes a Packer built for various hypervisors. Virtualbox and Hyper-V work already, but I cannot get Packer to boot in VMWare desktop (fusion in my case).

Packer template: controller/packer.pkr.hcl at main · playingfield/controller · GitHub

Error message: Unable to mount root fs on unknown-block(0,0)
