Yii2 + SQLite. php yii migrate can access db file, while controller can't

I have strange error on custom controller SQLSTATE[HY000] [14] unable to open database file which mean that SQLite pdo could not open db file.

However if I run yii commands in cli, there is no problem with db, and I can confirm that file is accessed and modified properly.

So how can it work, and not work at the same time? Is Yii using different dbs for cli and for app served with php yii serve? How could I debug which settings Yii is using to connect to db?

Edit: I'm using basic template. So /config/console.php reuse db definitions in /config/db.php. There is also /config/test_db.php which also reuse db.php but with different filename. I'm able to run migrations from cli on it too.

Edit2: Console.php
