Import-Export from External Vcenter6 unable to list instance.

Error retrieving VMs from VMware VC: Error retrieving VMs from the VMware VC 10.xxx.xxx.xxx datacenter DC-XXX: Cannot invoke "java.lang.Boolean.booleanValue()" because the return value of "com.vmware.vim25.VirtualMachineBootOptions.isEfiSecureBootEnabled()" is null

Cloudstack Management v4.22.0.0

The steps to reproduce the bug

What to do about it?

When tested on Cloudstack v4.20.0.0 there were no problems.
Are there other parameters that must be set in CloudStack or VCenter?
