部署在AWS Lambda的Spring Boot 3 GraphQL API遭遇HttpMessageNotReadableException

场景 #

使用spring-boot-starter-graphql和aws-serverless-java-container-springboot3将简单GraphQL API部署到AWS Lambda，前端搭配AWS HTTP API Gateway。本地Tomcat环境下请求可正常处理，但部署到Lambda后触发org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: No content to map due to end-of-input异常，排查三天未解决。

版本信息 #

• Serverless Java Container版本：2.0.0-M1
• 实现框架：Spring Boot 3
• Spring Boot版本：3.1.0
• 前端服务：HTTP API
• 部署方式：Console

预期行为 #

调用HTTP API Gateway的/graphql接口应返回200响应，示例curl命令：

curl 'https://[APIGATEWAY_URL]/graphql' -H 'Accept-Encoding: gzip, deflate, br' -H 'Content-Type: application/json' -H 'Accept: application/json' -H 'Connection: keep-alive' -H 'Origin: altair://-' --data-binary '{"query":"query example{\n  exampleQuery(input: { id: 1 }) {\n    ok\n  }\n}\n","variables":{}}' --compressed

实际行为 #

触发JSON解析错误，具体日志如下：

复现步骤 #

可通过仅包含5个类的项目复现该问题
