Post processor vagrant failing

Packer

MacOS 15.4.1
Packer v1.12.0
$ packer plugin installed
/Users/rwideman/.config/packer/plugins/github.com/hashicorp/ansible/packer-plugin-ansible_v1.1.3_x5.0_darwin_arm64

This code works.
packer {
required_plugins {
vmware = {
version = “>= 1.1.0”
source = “github.com/hashicorp/vmware”
}
vagrant = {
version = “>= 1.1.5”
source = “GitHub - hashicorp/vagrant: Vagrant is a tool for building and distributing development environments.”
}
}
}
source “vmware-vmx” “vmware” {
source_path = “~/Virtual Machines.localized/Debian12.vmx”
communicator = “ssh”
ssh_username = “vagrant”
ssh_password = “vagrant”
shutdown_command = “sudo poweroff”
}

build {
sources = [“source.vmware-vmx.vmware”]
post-processor “vagrant” {
keep_input_artifact = false
output = “debian12.box”
}
}

Now I am trying to use a box already uploaded to HCP and everything works until post-processor “vagrant” starts.
source “vagrant” “debian12-arm64” {
source_path = “rwideman/debian12-arm64”
provider = “vmware_desktop”
communicator = “ssh”
add_force = true
#box_name = “debian12-arm64”
}

build {
sources = [“source.vagrant.debian12-arm64”]
provisioner “shell” {
inline = [
“echo Updating Packages”,
“sudo apt update && sudo apt upgrade -y”,
]
}
provisioner “shell” {
inline = [“sudo reboot”]
expect_disconnect = true
pause_before = “1m”
}
post-processor “vagrant” {
keep_input_artifact = false
output = “/Users/rwideman/code/packer/debian12/debian12-arm64.box”
}
}
