Packer: Build 'vsphere-iso': error mounting an image [datastore] folder//file.iso is not a valid iso path
Overview of the Issue
During build the ISO is downloaded and copied to the datastore, VM created, hardware customized. However, during mounting of the ISO an error thrown:
2020/09/04 23:39:39 machine readable: vsphere-iso,error []string{"error mounting an image '[QXS4-DS-01] packer_cache//a9e6afb56387f189d0c6f6665708a1d53e2d8fd6.iso': [QXS4-DS-01] packer_cache//a9e6afb56387f189d0c6f6665708a1d53e2d8fd6.iso is not a valid iso path"}
I checked the file is indeed exist at path: [QXS4-DS-01] packer_cache/a9e6afb56387f189d0c6f6665708a1d53e2d8fd6.iso. I even was able to mount by adding cdrom and copying path into "CD/DVD Media".
Dual slash results in an error in the GUI. It will refuse to accept it.
Changed to the single slash allows to mount the ISO.
P.S. When using double slash clicking on something else and then on CD/DVD Media path (few times), will result in vCenter eventually accepting the double slash and allow click okay. But when I went back to edit it again, it shows as a single slash.
Reproduction Steps
Simply running packer build on VMware 6.5
Packer version
1.6.2
Simplified Packer Buildfile
Operating system and Environment details
Packer running on Ubuntu 18.04.4 LTS connecting to vCenter (vSphere Client version 6.5.0.32000)

Could you please assist in figuring out what is causing this error? Let me know if other information needed.

I've also tried to use "iso_paths" and received the same error. I downloaded the ISO onto the datastore, ran sha256sum on them to validate their integrity. Then I added "iso_paths" to the builders file.
"iso_paths": [
"[QXS-DS-03] ISO/Ubuntu/ubuntu-20.04.1-live-server-amd64.iso"
],
Full file that I tried to run:

Hey there, thanks for reaching out! This was reported before here https://github.com/hashicorp/packer/issues/9846 and fixed by https://github.com/hashicorp/packer/pull/9855 and the fix will be in the next release.
Until then, you can use the artifacts from the PR to run the build. Here they are: https://app.circleci.com/pipelines/github/hashicorp/packer/6945/workflows/2ebe6433-53dd-40e8-b8fe-0b7cf84e2cf2/jobs/78129/artifacts
Let me know is there's anything wrong with your build. I'm closing this issue for now.
