pg_upgrade and generated column

Hi,

O/S is
Rocky Linux release 9.5

Command is
nohup time /usr/pgsql-16/bin/pg_upgrade -d /pgdata/pgsql/15/data -D
/pgdata/pgsql/16/data -b /usr/pgsql-15/bin -B /usr/pgsql-16/bin --retain
2>&1&

and
pg_upgrade fails with error:

...
pg_restore: from TOC entry 226; 1259 17061 TABLE m_access_cert_campaign
iamappadmin
pg_restore: error: could not execute query: ERROR: column "objecttype" in
child table must not be a generated column
Command was:
-- For binary upgrade, must preserve pg_type oid
SELECT
pg_catalog.binary_upgrade_set_next_pg_type_oid('17063'::pg_catalog.oid);
...

I can find some descriptions of the problems from internet,
but there are no instructions or recommendations on postgres.org,
what is the "correct" way to upgrade a db if it has a "generated column".
Some suggestion pls. Can i use pg_upgrade at all?
