19c Clone from Remote PDB fails

I am trying to clone a pdb from one container to another. Both containers are on the same server. I have a user in cdb1 with create pluggable database privilege as well as sysoper privilege (per oracle documentation). I have a database link from cdb2 to cdb1 using that user.
