Steps to upload file with OpenAssessment to Amazon AWS

[Christos Bellos]

Hi, I am trying to set up the OpenAssessment on the AWS Instance that I initiated. 

I have followed the steps described here: http://edx-ora-2.readthedocs.io/en/latest/architecture/fileupload.html

but for the "FILE_UPLOAD_STORAGE_BUCKET_NAME" I have used the default edxuploads.

I entered then the AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY to the lms.auth.json and the cms.auth.json, but when I try to upload a file, I get the following error at the inspect element of my browser: Permission Denied

I have checked multiple the credentials and I am sure I entered them correctly. 

Also, I tried to create a new bucket to replace the default edxuploads, but still the same error.

Could you please help me on this?

For the file upload to S3, I created a new bucket and added the following CORS configuration:

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

    <CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">

        <CORSRule>

            <AllowedOrigin>*</AllowedOrigin>

            <AllowedMethod>GET</AllowedMethod>

            <AllowedMethod>POST</AllowedMethod>

            <AllowedMethod>PUT</AllowedMethod>

            <AllowedMethod>HEAD</AllowedMethod>

            <AllowedHeader>*</AllowedHeader>

        </CORSRule>

    </CORSConfiguration>

However, I still get these 2 errors in my log file:

Could you please help me on this? I do not have other alternatives or thoughts...
