It seems like $config of type array is incompatible with the declared type string of property $config.

The property password does not exist on nebula\component\database\connector\Connector. Did you maybe forget to declare it?

The property user does not exist on nebula\component\database\connector\Connector. Did you maybe forget to declare it?
