My program has a basic function for adding datas to database but when the code gives an error when it is compiled.

QSqlDatabase db= QSqlDatabase::addDatabase("QMYSQL");
db.setHostName("localhost");
db.setUserName("root");
db.setPassword("*******");
db.setDatabaseName("databasename");
db.setPort(1111);
if(db.open()){
qDebug()<<"connected";
}

console/config/main.php is default. Problem is on localhost (win7x62) and remote host (debian).
I had the same situation with the attempt to migrate rbac
(yii migrate --migrationPath=#yii/rbac/migrations)
What is causing the problem ??? my ignorance ;)?

Well, as you error message says, you are trying to set unknown property 'errorAction'. I suppose you are using the same error component config here in console app as in web app. See if there is
[
'components' => [
'error' => [
'errorAction' => ...
]
]
]
in your console app config. There shouldn't be 'errorAction'.

Thanks,
I moved from frontend/config and backend/config code
'errorHandler' => [
'errorAction' => 'site/error',
]
to common/config. Frontend and backend app did not have a problem with that, but console yes. After rollback is ok.
