Issue on Calling AWS JAVA LAMBDA From Another Java Lambda

I want to call a aws lambda which is in JAVA from another lambda. I go through the below result "https://stackoverflow.com/questions/36483042/how-to-call-an-aws-java-lambda-function-from-another-aws-java-lambda-function-wh"

I implemented the code like below.

First I create one AWS lambda java project. My code is like below

import com.amazonaws.services.lambda.AWSLambdaAsyncClientBuilder;
import com.amazonaws.services.lambda.invoke.LambdaInvokerFactory;
import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.runtime.RequestHandler;

public class LambdaFunctionHandler implements RequestHandler<Object, String> {

    @Override
    public String handleRequest(Object input, Context context) {
        context.getLogger().log("Input: " + input);

        FineGrainedService fg = LambdaInvokerFactory.builder()
                .lambdaClient(
                        AWSLambdaAsyncClientBuilder.standard()

                        .build()
                )
                .build(FineGrainedService.class);

        context.getLogger().log("Response back from FG" + fg.getClass());

        String fgRespone = fg.callFineGrained("Call from Gateway");
        context.getLogger().log("fgRespone: " + fgRespone);

        // TODO: implement your handler
        return "Hello from Gateway Lambda!";
    }
}

As per the above link created one interface

import com.amazonaws.services.lambda.invoke.LambdaFunction;

public interface FineGrainedService {
     @LambdaFunction(functionName="SimpleFineGrained")
     String callFineGrained(String input);
}

Again created another lambda to call the above lambda

import com.amazonaws.services.lambda.AWSLambdaAsyncClientBuilder;
import com.amazonaws.services.lambda.invoke.LambdaInvokerFactory;
import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.runtime.RequestHandler;

public class LambdaFunctionHandler2 implements RequestHandler<Object, String> {

    @Override
    public String handleRequest(Object input, Context context) {
        context.getLogger().log("Input: " + input);

        FineGrainedService fg = LambdaInvokerFactory.builder()
                .lambdaClient(
                        AWSLambdaAsyncClientBuilder.standard().build()
                )
                .build(FineGrainedService.class);

        context.getLogger().log("Response back from FG" + fg.getClass());

        String fgRespone = fg.callFineGrained("Call from Gateway");
        context.getLogger().log("fgRespone: " + fgRespone);

        // TODO: implement your handler
        return "Hello from Gateway Lambda!";
    }
}

Added maven dependency to pom.xml

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-lambda</artifactId>
 </dependency>

Added lambda invoke permission to my current role. Then I uploaded the code to the AWS. But when I am testing this I am getting an error like below.. Please could you help me to figure out this?

It would be grateful if anyone can help to get this... Or any other way to call a lambda from another lambda using JAVA
