Is it possible to strongly type the events in much the same way as nest-emitter?

UnhandledPromiseRejectionWarning: TypeError: emiterInstance.on is not a function

Please update the @nestjs/common to fix the axios vulnerabilities (GHSA-cph5-m8f7-6c5x).

@nestjs/common have merged it into the core now: nestjs/nest#8030

For someone who needs a quick fix until this gets resolved:

"resolutions": { "axios": "0.21.4" },

I am having issues using nest-event. I have NestEventModule imported in app.module

imports: [ NestEventModule, ... ]

Then I am injecting it in my service:
constructor(private nestEvent: NestEventEmitter)

And finally I emit an event:
this.nestEvent.emit('TESTEMIT');

This emit is triggered when I do a GET request to my API.

But all I get is this error:

error:   ┏ Cannot read property 'has' of undefined: +6ms

It happens right here: if (!this.nestEvent.getEmitters().has(emitter)) {

I tried creating different emitter classes with @emitter() decorator but it doesn't help.
I also tried executing configure() method manually as I've seen in the code it is used for setting emitters in a Map, also doesn't help.

Any suggestions? Thanks in advance
