使用java sdk

Question

尝试使用java sdk以异步模式调用AWS Lambda时，我看到以下错误： -

ERROR [2018-04-20 03:07:09,053] io.dropwizard.jersey.errors.LoggingExceptionMapper: Error handling a request: 4e552086b3525fbf

我使用过AWS SDK的1.11.106版。我的pom.xml如下所示

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.amazonaws</groupId>
            <artifactId>aws-java-sdk-bom</artifactId>
            <version>1.11.106</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>
<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-lambda</artifactId>
</dependency>`

我调用产生此错误的java代码如下

AWSLambda client = AWSLambdaClientBuilder.standard()
                .withCredentials(new DefaultAWSCredentialsProviderChain())
                .withRegion("us-west-2")
                .build();
InvokeRequest request = new InvokeRequest().withFunctionName("streamConsumer").withInvocationType("Event").withLogType("Tail").withClientContext("service").withPayload(ByteBuffer.wrap(json.getBytes("UTF-8"))).withQualifier("1");
InvokeResult response = client.invoke(request);
