Error: local variable 'mount_point' referenced before assignment vfuse 3.0.0

Given:

• MacBookPro15,2 running macOS Catalina 10.15.4 (19E287)
• VMware Fusion 11.5.3 (not the Pro edition)
• AutoDMG 1.10b (587)
• python 3.7.7
• vfuse 3.0.0
• macOS 10.15.4 .dmg created using AutoDMG called osx-10.15.4-19E287.apfs.dmg
• and much gratitude that you provided vfuse in the first place.

...when I run...

% vfuse -i osx-10.15.4-19E287.apfs.dmg

...I was expecting a virtual machine to be generated with the default name macos-vm.vmwarevm.

Actually I get the following error and no VM is generated:

Mounting osx-10.15.4-19E287.apfs.dmg

    mount_point, disk_id, volume_kind = mount_dmg(source_dmg)

    return mount_point, disk_id, volume_kind

hdiutil shows the .dmg as mounted after the failure. Cleaning that up using

hdiutil info | grep /dev/disk | grep partition | cut -f 1 | xargs -I {} hdiutil detach {}

...and retrying vfuse produces the same result.
