Note that after schema change you have to restart the server.

Please advise whether you see such exceptions after restarting the server, and if you do, whether the database has errors when checked by the Doctor.

Yes, I still see that exception after restarting the server.

However, the exceptions disappeared after I checked with the Doctor.

Thanks!!
