Missing vmx file? Packer or Vagrant issue?

I’m not sure if it’s a Packer problem or belongs more to Vagrant but I have a problem with a newly created box.

As an exercise with packer/vagrant I’m trying to make a RockyLinux box, and use packer with the vmware-esxi plugin for that. The box creation all seems to work fine, and my box created is also being pushed to vagrant cloud.

However, when I create a Vagrantfile with a call to this vagrant cloud box I get the message that no .vmx file is present.

gerrit@gerrit-NUC7i5DNHE:~/Repo/ansible-for-devops$ sudo vagrant up

Bringing machine 'default' up with 'vmware_esxi' provider...
==> default: Virtual Machine will be built.
VMware ovftool 4.4.3 (build-18663434)
There was an error.
  Unable to open /root/.vagrant.d/boxes/gzeel-VAGRANTSLASH-rocky8/1.0.3/vmware_desktop/*.vmx

Where am I doing something wrong?
