RabbitMQ EventPattern don't work

[cholombytko]

Is there an existing issue for this?

• [X] I have searched the existing issues

Current behavior

I have error in terminal

ERROR [Server] There is no matching event handler defined in the remote service. Event pattern: add_subscriber

Minimum reproduction code

https://github.com/GenesisEducationKyiv/software-engineering-school-4-0-cholombytko/blob/hw6/monolith/subscription/src/app.controller.ts

Steps to reproduce

1. docker-compose up --build
2. Create POST request to http://localhost:3000/subscribe with body:

   {
   "email": "example@email.com"
   }

Expected behavior

Mine expected working workflow is:

1. Creating POST request
2. Emitting event with email data;
3. Store this data in PostgreSQL database
