I'm unable to run my springboot service (gradle) as it fails during startup while trying to connect to a grpc server. Earlier my service was on grpc version 1.24.0, updated it to 1.27.1.
Function to connect to grpc server -
public static ManagedChannel getGrpcChannel(String host, int port, String serviceConfigJson) {
return NettyChannelBuilder.forAddress(host, port)
.enableRetry()
.defaultServiceConfig(GrpcUtils.getServiceConfig(serviceConfigJson))
.usePlaintext()
.build();
}
Getting below exception -
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

My service was working until earlier on local. This is what I've tried so far -
- I have checked for netty default port and checked all listening ports as well. Didn't find any process that would block the grpc server startup.
- Tried downgrading and upgrading the version of grpc libraries that I'm using.
What am I missing here?
