AwsProxyResponse class is generating response JSON which is rejected by API gateway with Malformed error

[Chiranjibeem]

We are calling java lambda from api gateway and in cloudwatch logs i can see internal server error is coming,

After going through the logs and support team i got to know that AwsProxyResponse class is generating response JSON which is rejected by API gateway with Malformed error

Json generated is using field name base64Encoded instead of isBase64Encoded

The property is named explicitly
https://github.com/aws/serverless-java-container/blob/main/aws-serverless-java-container-core/src/main/java/com/amazonaws/serverless/proxy/model/AwsProxyResponse.java#L122 so I wonder what makes the serialization ignore it in your case.

Serverless Java Container version: 2.0.0-M2

Implementations: Spring Boot

Framework version: SpringBoot 3.2.0

Frontend service: AWS API Gateway

Deployment method: Serverless Framework

Scenario - When we are trying to invoke lambda with proxy integration from apigateway, apigateway is throwing malformed error

Expected Behaviour - as part of lambda response, api gatway is expecting isBase64Encoded value but from lambda response we are getting only base64Encoded key

Actual Behaviour - isBase64Encoded should come ans statusDescriptions also not required as per api gateway

Stepa to reproduce -
Create a api gatway
Call lambda ( rerurn type should be AwsProxyResponse)
Invoke Lambda from ApIGAteway

Can you please try reproducing it using our sample https://github.com/aws/serverless-java-container/tree/main/samples/springboot3/pet-store?

We have multiple unittests in place that cover it so I can only imagine it's related to specific configurations inside your application.
