Workaround
1. The "vSphere API" and "Storage APIs" features are not licensed for the backup target ESXi host, according to the VMWare KB: https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1021175 The Data Protection APIs are included with all licensed vSphere editions: Standard, Enterprise and Enterprise Plus.

3. Restart the DS-Client service
