RMQ Every other request responds "There is no matching message handler defined in the remote service."

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

Currently every other request works, and every other is being marked as “Unroutable (drop)” by RabbitMQ and responding with “There is no matching message handler defined in the remote service.”.

Minimum reproduction code

https://github.com/rittaschool/ritta-server

Steps to reproduce

1. ./update.sh
2. docker-compose -f docker-compose.dev.yml up
3. http://localhost:15672 -> guest:guest
4. Create new users: users:users and auth:auth
5. Restart (CTRL+C old process, run step 2)
6. http://localhost:3000/docs
7. /api/v1/users
8. Run twice

Expected behavior

The list of users should be sent every time.

Other

Authentication part of the application works fine without this problem. I am pretty sure that the problem lies somewhere inside the apps/users part of the repository.

I found the answer from the Discord server!

The solution was to create a own queue for every microservice (and and a own event bus). https://github.com/rittaschool/ritta-server/commit/b837fd9f73a3d1163c02c2b5aef6102c5acb2334
