I was working with Microservices but couldn't invoke methods

Question

Hi,

 

I am working with .Net Core 3.1 and got stuck in a situation. I am not able to invoke a consumer method that needs to be invoked when I call a particular event. Example is a test Banking application where I call Post method in banking API for transferring and the request gets logged in RabbitMQ and then an event should be fired to pick the data and save it to the database.

 

 I am posting the entire code. This is just a test app which needs a small refactoring, please let me know what I am doing wrong here.
