Fail to get binary data.

See original GitHub issue

(Region : ap-northeast-2, seoul)

What I did

Set API Gateway Binary Support, case of Conetent-type : application/octet-stream.
Add binary types parameter on createServer from aws-serverless-express
Set request header Accept with application/octet-stream.
Send binary data like res.send(data);. I checked isBase64Encoded is true.

What I expected

I expected to got binary data that decoded by api gateway

What I actually got

I got base64 encoded values.

And also, when I revert commit b61d288 , I could get binary data.

What’s wrong with me?

It’s true that isBase64Encoded flag is not documented for output but it’s discussed e.g. here: https://forums.aws.amazon.com/thread.jspa?messageID=759454

“For the Lambda proxy case, you can send the base64 encoded flag with your response from Lambda to tell API Gateway if your response body is base64 encoded, however, you need to send an Accept header which is defined in the binaryMediaTypes in order to receive a binary response from API Gateway”

Don’t do this res.setHeader('isBase64Encoded').
