无法执行使用Micronaut和Graal构建的AWS Lambda函数：解码JSON流时出错

Question

我使用Graal和Micronaut构建了一个原生java AWS Lambda函数，如下所述

将其部署到AWS Lambda（自定义运行时）后，我无法成功执行它。

AWS显示的错误是：

{
  "errorType": "Runtime.ExitError",
  "errorMessage": "RequestId: 9a231ad9-becc-49f7-832a-f9088f821fb2 Error: Runtime exited with error: exit status 1"
}

AWS日志输出为：

START RequestId: 9a231ad9-becc-49f7-832a-f9088f821fb2 Version: $LATEST
01:13:08.015 [main] INFO  i.m.context.env.DefaultEnvironment - Established active environments: [ec2, cloud, function]

END RequestId: 9a231ad9-becc-49f7-832a-f9088f821fb2

RequestId: 9a231ad9-becc-49f7-832a-f9088f821fb2 Error: Runtime exited with error: exit status 1
Runtime.ExitError

但是当我使用本地测试它时

echo '{"value":"testing"}' | ./server

我得到了

01:35:56.675 [main] INFO  i.m.context.env.DefaultEnvironment - Established active environments: [function]
{"value":"New value: testing"}

功能代码为：

@FunctionBean("user-data-function")
public class UserDataFunction implements Function<UserDataRequest, UserData> {

    private static final Logger LOG = LoggerFactory.getLogger(UserDataFunction.class);

    private final UserDataService userDataService;

    public UserDataFunction(UserDataService userDataService) {
        this.userDataService = userDataService;
    }

    @Override
    public UserData apply(UserDataRequest request) {
        if (LOG.isDebugEnabled()) {
            LOG.debug("Request: {}", request.getValue());
        }

        return userDataService.get(request.getValue());
    }
}

UserDataService是：

@Singleton
public class UserDataService {

    public UserData get(String value) {
        UserData userData = new UserData();
        userData.setValue("New value: " + value);

        return userData;
    }
}

为了在AWS控制台上测试它，我配置了以下测试事件：

{ "value": "aws lambda test" }

注：我向AWS Lambda上传了一个zip文件，其中包含“服务器”和“引导”文件，以允许如前所述的“自定义运行时”。

我做错了什么？

提前谢谢。

编辑：添加了AWS控制台上使用的lambda测试事件。

好的，我想出来了。我刚刚更改了这个引导文件

#!/bin/sh
set -euo pipefail
./server

到这个

#!/bin/sh
set -euo pipefail

# Processing
while true
do
  HEADERS="$(mktemp)"
  # Get an event
  EVENT_DATA=$(curl -sS -LD "$HEADERS" -X GET "http://${AWS_LAMBDA_RUNTIME_API}/2018-06-01/runtime/invocation/next")
  REQUEST_ID=$(grep -Fi Lambda-Runtime-Aws-Request-Id "$HEADERS" | tr -d '[:space:]' | cut -d: -f2)

  # Execute the handler function from the script
  RESPONSE=$(echo "$EVENT_DATA" | ./server)

  # Send the response
  curl -X POST "http://${AWS_LAMBDA_RUNTIME_API}/2018-06-01/runtime/invocation/$REQUEST_ID/response"  -d "$RESPONSE"
done

如本文所述
