I ask for your help, dear experts!
problem solved. It was necessary to inject the container using a setter, an example in the answers

Answer 1

You all perfectly told in the previous thread.
If it's not clear, I'll try to summarize.
It is not necessary to inject the mailer service into the controller, because the controller in symphony implements ContainerAwareInterface and the service can be accessed using the get() method.
If for some reason your controller does not inherit from the standard symphony controller, you must implement ContainerAwareInterface.
If you inherit the standard symphony controller, and make your controller a service, you must inject the container using a setter.
Configuration example:

my.controller.service:
        class: MyCompany\MyBundle\Controller\MyController
        calls:
            - [setContainer, ["@service_container"]]

Answer 2

mailer service. Inject it. If there is no such service, then it's a problem. This service is located in symfony/SwiftmailerBundle
