While using .registerAsync with custom controller, custom controller not working and path is ignored

[murbanowicz]

I found this really weird issue. When using useFactory / registerAsync, the custom controller does not work properly.

I have to use configuration, so I moved to async creation and I hit this issue which I cannot even workaround :/

If custom controller is passed to the options while using registerAsync, the controller is not used, but the base prom controller is being used and on top of that the path is being ignored completely.

Can you provide a minimal reproduction please?

[murbanowicz]

Yes please. Simple test showcasing the issue. https://github.com/murbanowicz/nestjs-prometheus/blob/register-async-controller-issue/test/custom-controller.spec.ts

I went through the code but did not find anything obvious :/

[willsoto]

Thanks. I will take a look hopefully later today or tomorrow

[murbanowicz]

Thanks! That you for such a quick reaction.

Out of curiosity, do you need to actually inject anything into the controller via the useFactory?

[murbanowicz]

I need to inject config to set custom labels. I could workaround it but it is still a bug (which I can't figure out so far while looking through the code :/

[willsoto]

Just to be clear, you are trying to inject something into the controller itself?

The whole reason the "custom controller" feature was added was to support Fastify. There really isn't any logic in that controller. Setting custom labels you can do via configuration only.

It's a mistake that I allow it to go in the main options, it should only exist outside the useFactory, etc. Like so:

PrometheusModule.registerAsync({
  controller: CustomController,
  useFactory() {
    // whatever goes here
    return {};
  },
});
