Invalid Vagrantfile with local vagrant cloud repository

[wysiayg]

Overview of the Issue

Maybe I'm missing something obvious here, but if a different Vagrant repository is used with the builder, the generated Vagrantfile does not work. In my case, JFrog's Artifactory is used to host a local box repository.
To resolve a box, a URL with the following format: https://{Artifactory URL}/api/vagrant/{vagrantRepoKey}/{boxName} is used and resolves to the latest version. The box is added correctly by packer. However, the created Vagrantfile looks as follows:

Vagrant.configure("2") do |config|
  config.vm.define "source", autostart: false do |source|
	source.vm.box = "https://<local_adress>/artifactory/api/vagrant/vagrant-repo/debian-12.5"
	config.ssh.insert_key = false
  end
  config.vm.define "output" do |output|
	output.vm.box = "debian-12.5"
	output.vm.box_url = "file://package.box"
	config.ssh.insert_key = false
  end
  config.vm.synced_folder ".", "/vagrant", disabled: true
end

This results in the following error messages:

Considering how the Vagrantfile is created, source.vm.box = "{{.BoxName}}" would resolve this issue and allows a correct run.
As a temporary workaround I provided an adjusted template:

Vagrant.configure("2") do |config|
  config.vm.define "source", autostart: false do |source|
	source.vm.box = "{{.BoxName}}"
	config.ssh.insert_key = {{.InsertKey}}
  end
  config.vm.define "output" do |output|
	output.vm.box = "{{.BoxName}}"
	output.vm.box_url = "file://package.box"
	config.ssh.insert_key = {{.InsertKey}}
  end
  {{ if ne .SyncedFolder "" -}}
  		config.vm.synced_folder "{{.SyncedFolder}}", "/vagrant"
  {{- else -}}
  		config.vm.synced_folder ".", "/vagrant", disabled: true
  {{- end}}
end

Reproduction Steps

1. Setup a local vagrant repository
2. Add a box
3. Use the Buildfile provided below
4. Run packer with PACKER_LOG=10 packer build --debug . to see the appropriate error messages.

Plugin and Packer version

Packer v1.9.4
Plugin: v1.1.1_x5.0_linux_amd64

Simplified Packer Buildfile

packer {
  required_version = ">= 1.7.0"
  required_plugins {
    vagrant = {
      version = ">= 1.0.2"
      source  = "github.com/hashicorp/vagrant"
    }
  }
}

source "vagrant" "vm" {
  communicator    = "ssh"
  source_path     = "https://{Artifactory URL}/api/vagrant/{vagrantRepoKey}/{boxName}"
  box_name        = "{boxName}"
  teardown_method = "destroy"
}

build {
  sources = ["source.vagrant.vm"]
}
