Kafka microservice health check does not work

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

Configuring a microservice ping check, like:

       this.kafka.pingCheck('KAFKA', {
          name: configService.getKafkaClientName(),
          transport: Transport.KAFKA,
          options: {
            client: {
              brokers: configService.getKafkaHost(),
            },
            consumer: {
              groupId: configService.getKafkaGroupId(),
            },
          },
        });

The check will alway return “timeout of x ms exceeded” whatever how many timeout will be set.

But my service still working well with the same Microservice config.

Minimum reproduction code

       this.kafka.pingCheck('KAFKA', {
          name: configService.getKafkaClientName(),
          transport: Transport.KAFKA,
          options: {
            client: {
              brokers: configService.getKafkaHost(),
            },
            consumer: {
              groupId: configService.getKafkaGroupId(),
            },
          },
        });

Steps to reproduce

No response

Expected behavior

Health check should be return UP status when the kafka is able to connect

I think this is about as simple as it can get to reproduce described problem. I have not idea how to fix this.

If producerOnlyMode: true is the fix, it should be documented and make clear are the consequences using it (for me all seems to be working with that on localhost, but on k8 all starts to fail again like without producerOnlyMode).
