aws lambda function getting access denied when getObject from s3

Question

I am getting an acccess denied error from S3 AWS service on my Lambda function.

This is the code:

// dependencies
var async = require(\'async\');
var         


        

Answer 1

I was trying to read a file from s3 and create a new file by changing content of file read (Lambda + Node). Reading file from S3 did not had any problem. As soon I tried writing to S3 bucket I get 'Access Denied' error.

I tried every thing listed above but couldn't get rid of 'Access Denied'. Finally I was able to get it working by giving 'List Object' permission to everyone on my bucket.

Obviously this not the best approach but nothing else worked.
