Overview of the Issue

I have a Packer Script that uploads the result image to a Content Library. The first run, which has a unique name, will work without issue. When I re-run the script, without any changes, packer crashes.

Reproduction Steps

Build a packer script Run the packer script [run is successful] Run the packer script again [run will crash]

Packer version

From packer version

packer version
Packer v1.9.2

    content {
      name        = "my.template.0.1.0-rc"
      library     = "my content library"
      description = "Built by Packer..."

What I find interesting about this latest attempt is it says "...Importing VM template rhel8-base-0.3.1-rc, when in fact the name of the template is rhel8-base-0.3.1-rc-vm and the content library name is rhel8-base-0.3.1-rc

==> vsphere-iso.template: Importing VM template rhel8-base-0.3.1-rc to Content Library 'Local Testing Library' as the item 'rhel8-base-0.3.1-rc' with the description 'Packer imported rhel8-base-0.3.1-rc-vm VM template'...
