Migration - Failed to instantiate component or class "db" in console Yii2 - php

Question

I am new to Yii2 and need to set up an existing project. I am at the stage where I would like to migrate tables to the database using the console. I have a database connection in Yii, everything in config is specified correctly. However, I get an error in the console when I try to migrate the tables:
Exception 'yiibaseInvalidConfigException' with message 'Failed to instantiate component or class "db".'
I have already searched Google and have not found a solution to this problem.
Here some code:
