getObject from aws s3 got gibberish

Question

in our project we have 1 service that uploads a local csv to s3, and I am working on another service which downloads csv that's uploaded using nodejs. I got gibberish in the content as i try to print the string of content (small csv). code :

 s3.getObject( { Bucket: mybucket, Key:mykey }, function(err,data){ console.log(data.Body.toString()) ; }) 

I have checked the data object that in the callback and found the type for buffer of data is unit8Array. I guess that's the cause. Does anyone know how I can control the type of buffer to be String? or is it something that needs to be changed during upload?

Answer 1

This is solved on the file upload side which is written in java. it was using AmazonS3EncryptionClientBuilder instead of AmazonS3ClientBuilder. as a result data coming back when downloading is encrypted that's why its gibberish. so it was not caused by buffer type
