venus deployment is missing the db sync process

[howard lee]

After the venus deployment is complete, there is an error message in the venus_manager log, as shown below:
(Background on this error at: https://sqlalche.me/e/14/f405): sqlalchemy.exc.ProgrammingError: (pymysql.err.ProgrammingError) (1146, "Table 'venus.t_mo_custom_config' doesn't exist")

Enter the venus database and find that there is no database table in the venus database:
