Could this have anything to do with ovftool being used? OVFTOOL 4.2 works from my desktop to import to vSphere 6.7, but 4.3 fails with the same error message.
Known Issues in This Version
As of release 6.5 U1, the
--allowAllExtraConfigis no longer supported. The
Alloption never never worked as designed, so it was deprecated. The workaround is to use
--allowExtraConfiginstead to import additional configurations.
Try using --allowExtraConfig switch with OVFTOOL 4.3
