Overview of the Issue

I'm using Mac M1 and rely on VMWare Fusion (In Packer I'm using VMWare ISO builder) and vagrant as a post-processor.

Locally when using the generated box, everything works fine, however when I push the box to hashicorp cloud then use that box instead, it throws the following error:

Provider expected: vmware_fusion Provider of box: vmware_desktop (Somehow Packer just throws vmware_desktop all the time instead of vmware_fusion).

I'm unable to find a way to change this, what I tried was in the post-processor to do the following

post-processor "shell-local" {
  inline = [
    "echo '{ \"architecture\": \"arm64\" , \"provider\": \"vmware_fusion\" }' | jq '.' > output-fedora/metadata.json"
  ]
}

And while it modifies the file, still the file that gets placed in the generated vagrant box contains vmware_destkop instead.

What i do as a workaround is very manual, that is to extract the box, modify the file, tar compress the box again then push it but .. isn't there a way to avoid all that ? A way to specify that in the generated metadata.json file I need to use vmware_fusion as the provider ?
