Description

The loadbalance handler must be configured in consumer handler chain to choose provider instance.
But currently if users overwrite the handler chain configuration and forget to configure loadbalance handler (like below), the consumer may only print exception message in InvokerUtils.innerSyncInvoke() in DEBUG level. This is easy to be ignored and make the problem confusing.

  handler:
    chain:
      Consumer:
        default: qps-flowcontrol-consumer
