What is the root cause of 403 Forbibben error in Prod and how to solve it ?

Question

Hello,

I am trying to upload images from my heroku symfony(php) app to my bucket.
Can you help us check the root cause for such issues?
We always run into such S3 bucket access issue. It will be highly appreciated if you can help check for us.

S3Exception: S3ResponseError: 403 Forbidden

<?xml version="1.0" encoding="UTF-8"?>

I finally got through it. It was lack of permissions at AWS S3 side... So I followed this one  then only the first stage of this one \[github.com/KnpLabs/Gaufrette/issues/279#issuecomment-289338230]. Hope it will help !
