UnhandledPromiseRejectionWarning on invalid RMQ microservice pattern

[atte-backman]

Bug Report

Current behavior

When sending invalid JSON microservice pattern via RMQ, e.g. {ac, UnhandledPromiseRejectionWarning is being thrown:

(node:21109) UnhandledPromiseRejectionWarning: SyntaxError: Unexpected end of JSON input
    at JSON.parse (<anonymous>)
    at ServerRMQ.handleMessage (.../node_modules/@nestjs/microservices/server/server-rmq.js:61:29)
    at channel.consume (.../node_modules/@nestjs/microservices/server/server-rmq.js:54:51)

Expected behavior

This situation (exception) should be gracefully handled. For instance, when sending unknown event pattern the following is being produced:

[Nest] 21398   - 05/29/2019, 1:17 PM   There is no matching event handler defined in the remote service. +352291ms

Environment

Nest version: 6.2.4

 
For Tooling issues:
- Node version: 10.15.3
- Platform:  Ubuntu 16.04.6 LTS
