I suspect you already revoked public CREATE privilege in schema public.
Note where the fine manual says:

schema_name
The name of an existing schema. Each target_role must have CREATE privileges for each specified schema.

There was some debate previously about whether that restriction was a
good idea at all; and given this example, it seems like we definitely
shouldn't require it during a REVOKE.
