vSphere iso builder with datastore

Hey all;

Trying to get Packer up and running in the environment. First stage is getting it working with my vSphere environment.

I’ve got the builder setup, it connects to my vSphere, and I’ve uploaded the iso into a datastore, inside a folder.

source "vsphere-iso" "linux_centos" {
    [...]
    datastore           = "LebVM01-Leb-Alpha-P1"
    iso_url             = "[LebVM01-Leb-Alpha-P1] ISOs/CentOS-8.3.2011-x86_64-dvd1.iso"
    [...]
}

However, when I run the build, it comes back at me saying it can’t find the iso:

--> vsphere-iso.linux_centos: error downloading ISO: [source path error: stat /[LebVM01-Leb-Alpha-P1] ISOs/CentOS-8.3.2011-x86_64-dvd1.iso: no such file or directory]

I’ve confirmed in vSphere at the ISO is in the specified datastore, and the vm is being built in the same cluster and host that has that datastore.

So, any tips or insights on how to troubleshoot this?

Packer version 1.7.2
