I have a lambda function which fetches a file from s3 using the input key in event and needs to send the same to client. I am using the following function to get the file from s3
function getObject(key){
var params = {
Bucket: "my_bucket",
Key: key
}
return new Promise(function (resolve, reject){
s3.getObject(params, function (err, data){
if(err){
reject(err);
}
resolve(data.Body)
})
})
}
If I send the response of this promise (buffer) to context.succeed, it is displayed as a JSON array on front end. How can I send it as a file ? The files can be either ZIP or HTTP Archive (HAR) files. The s3 keys contain the appropriate extension. I am guessing it has got something to do with the "Integration Response" in API Gateway. But not able to figure out where to change
