PHP migration with managed MySQL

Hello,

When I try to run migrations on App Platform during deploy, php artisan migrate --force, I get the following error even though I granted for db_user: SELECT, GRANT OPTIONS on information_schema, and GRANT ALL on my_schema_name.

Error:

In Connection.php line 712: SQLSTATE[HY000] [1045] Access denied for user ‘db_user’@‘IP_ADDRESS’ (using password: YES) (SQL: select * from information_schema.tables where table_schema = my_schema_name and table_name = migrations and table_type = ‘BASE TABLE’)

In Connector.php line 70:
SQLSTATE[HY000] [1045] Access denied for user ‘db_user’@‘IP_ADDRESS’ (using password: YES)

Do you have any idea how to resolve this problem?
