Cannot serialize into SQSEvent- NPE on all accessors #107
Description
I am trying to deserialize the default SQS test vent into an SQSEvent class, but a NPE is always thrown when I try to access the records. Looking through previous issues, others noted this and pointed to a case sensitivity issue in jackson. Any progress on this issue?
Here's my dependencies:
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-lambda-java-core</artifactId>
<version>1.2.0</version>
</dependency>
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-lambda-java-events</artifactId>
<version>2.2.7</version>
</dependency>
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-sqs</artifactId>
<version>1.11.708</version>
</dependency>
The event:
{
"Records": [
{
"messageId": "19dd0b57-b21e-4ac1-bd88-01bbb068cb78",
"receiptHandle": "MessageReceiptHandle",
"body": "Hello from SQS!",
"attributes": {
"ApproximateReceiveCount": "1",
"SentTimestamp": "1523232000000",
"SenderId": "123456789012",
"ApproximateFirstReceiveTimestamp": "1523232000001"
},
"messageAttributes": {},
"md5OfBody": "7b270e59b47ff90a553787216d55d91d",
"eventSource": "aws:sqs",
"eventSourceARN": "arn:{partition}:sqs:{region}:123456789012:MyQueue",
"awsRegion": "{region}"
}
]
}
The accessor code:
public class App implements RequestHandler<SQSEvent, Object> {
public Object handleRequest(final SQSEvent input, final Context context) {
System.out.println(input.getRecords()); //<--- this line throws the exception
Map<String, String> headers = new HashMap<>();
headers.put("Content-Type", "application/json");
headers.put("X-Custom-Header", "application/json");
return new GatewayResponse("SUCCESS", headers, 200);
}
}
And the exception:
Running helloworld.AppTest
Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.059 sec <<< FAILURE!
successfulResponse(helloworld.AppTest) Time elapsed: 0.007 sec <<< ERROR!
