Creation of events failing when running tests through another handler

I am trying to use `aws-lambda-java-tests`, but I am unable to deserialize objects to pass to the test cases. I receive ` java.lang.ClassNotFoundException: com.amazonaws.services.s3.event.S3EventNotification$S3EventNotificationRecord`.

This might be related to issue ##262

I am having a simple lambda with two entry points, where one is just an entry to run test cases on the other one. However, I am encountering the above issue when I am trying to create an `s3Event ` from `EventLoader.loadS3Event`

Please let me know if there is a way in which I can fix this problem, or if there exist any workarounds to it. Thanks

I am using
`aws lambda invoke --function-name aws-helloworld-junt5-test --payload file://AWSTestingHelloWorld/src/test/resources/events/put.json response2.txt
`
Here is my Lambda code

```

import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.runtime.RequestHandler;
import com.amazonaws.services.lambda.runtime.events.S3Event;

import org.junit.platform.launcher.core.LauncherDiscoveryRequestBuilder;
import org.junit.platform.launcher.Launcher;
import org.junit.platform.launcher.LauncherDiscoveryRequest;
import org.junit.platform.launcher.core.LauncherFactory;

import static org.junit.platform.engine.discovery.DiscoverySelectors.selectClass;

import org.junit.platform.launcher.listeners.SummaryGeneratingListener;
import org.junit.platform.launcher.listeners.TestExecutionSummary;

import java.util.List;

public class AwsHelloWorldJunit5 implements RequestHandler {

public String handleRequest(S3Event s3Event, Context context) {

System.out.println("executing the lambda");
return null;
}

@Override
public String handleRequest(Object s3Event, Context context) {
//invoke the Junit Test.
final LauncherDiscoveryRequest request =
LauncherDiscoveryRequestBuilder.request()
.selectors(selectClass(AwsHelloWorldJunit5Test.class))
.build();

final Launcher launcher = LauncherFactory.create();
final SummaryGeneratingListener listener = new SummaryGeneratingListener();

launcher.registerTestExecutionListeners(listener);
launcher.execute(request);

TestExecutionSummary summary = listener.getSummary();
long testFoundCount = summary.getTestsFoundCount();
List failures = summary.getFailures();
System.out.println("getTestsSucceededCount() : " + summary.getTestsSucceededCount());
failures.forEach(failure -> System.out.println("failure - " + failure.getException()));
return "testFoundCount = " + testFoundCount + " failures = " + failures.size();
}
}
```

And here is my lambda test code
```
import com.amazonaws.services.lambda.runtime.events.S3Event;
import com.amazonaws.services.lambda.runtime.tests.EventLoader;
import org.junit.jupiter.api.Test;

import java.io.IOException;

import static org.junit.jupiter.api.Assertions.assertEquals;

public class AwsHelloWorldJunit5Test {

@Test
public void testInjectSQSEvent4() throws IOException {
System.out.println("before running TC4");
S3Event s3Event = EventLoader.loadS3Event("events/put.json");
String output = (new AwsHelloWorldJunit5()).handleRequest(s3Event, null);
System.out.println("TC4: printing the output = " + output);
assertEquals("Hello World1", output);
}
}

```
