Getting an error when attempting to upload to latest Java Realms

Whenever I attempt to upload a saved realm from a newer version of Java to a Java Realms, I get an Upload Failed! (-1).  I've tried a number of saves (1.19.4 and 1.20.1).  Same results.  Older saves upload without issue (1.19.3 and earlier are all fine).  Local and LAN versions of the save that fails to upload to realms work just fine.

 

I've searched the forums and couldn't find anyone else reporting the same issue as me.  Maybe I just wasn't wording it right.
