isBase64Encoded field missing from APIGatewayProxyResponseEvent

[dsilvasc]

The field isBase64Encoded from https://docs.aws.amazon.com/apigateway/latest/developerguide/set-up-lambda-proxy-integrations.html#api-gateway-simple-proxy-for-lambda-output-format is not present in APIGatewayProxyResponseEvent.

It's present in the AwsProxyResponse class from https://github.com/awslabs/aws-serverless-java-container though -- also an Amazon project. Maybe these two projects could share API Gateway data types?

I'm facing the same issue. Also, I miss the isBase64Encoded attribute on the request object too.
I think it would be easy to fix. If you guys don't mind I can send you a PR with a patch.

I've overlooked the request object. Indeed, the isBase64Encoded is there.
But, off course, the response object still misses this attribute.

I've juste created a lambda returning application/pdf data encoded as base64.

APIGatewayProxyResponseEvent response = new APIGatewayProxyResponseEvent();
            response.setStatusCode(200);
            HashMap<String, String> headers = new HashMap();
            headers.put("Content-Type", "application/pdf");
            response.setHeaders(headers);
            response.setIsBase64Encoded(true);
            response.setBody(base64Document);

In the api gateway logs, I cannot see anywhere isBase64Encoded in the response received from lambda. Where is it supposed to be set ?

My client keeps receiving response from api gateway as base64 encoded string. I would like the data to be sent as binary data.

The Accept header sent by my client contains "application/pdf" as the only one parameters and the mediaType in setting of the api gateway is also "application/pdf" (ven tried it with /).

Could you help ?
