Hi,
 
I tried your reproduction steps but cannot get the same error.
 
Can you please provide some more information about the version
of publisher and subscriber you used ?
 
Just to confirm, did you use the PG15 beta1 or earlier PG15 version
as the publisher and use PG15 beta2 as the subscriber ?
 
Best regards,
Hou zj
