vCenter 6.7 backup config error "union with a field not required for this case = end_time"

[LaserChase]

I upgraded a vCenter Server Appliance 6.0 to 6.7 and things seem to be going well.  I have attempted to configure VCSA configuation backups via the Appliance Management interface but receive the following error.

Structure com.vmware.appliance.recovery.backup.job.details.info has a union with a field not required for this case = end_time

First I tried via FTP to a NAS, then when getting the error I setup a FileZilla FTP server on a PC and received the same result.  The user account has full RW access and the backup does create the folder structure before quitting.  FileZilla logs show the vCenter logging in via FTP (below).  I'm seeking information on how to troubleshoot this further.  Thank you.

Hi,  did you end up resolving this error?

[datacenterdude]

Interested is this was resolved or not, and if so, what the resolution was.  I'm running into the same issue.  Trying to do backup (having to consolidate vCenter and PSC) prior to upgrade to 7.0.

Try to edit /storage/applmgmt/backup_restore/backup-history.json . Have backup of that file.

And either remove the complete entry for backup id Or else change the state to FAILED .

This issue should ideally be fixed in 7.0 U3 and later versions
