What is the error message when a large upload fails?

Hello,

Regarding the file size limits through Amazon CloudFront,

> The maximum size of a single file that can be delivered through Amazon CloudFront is 30 GB. This limit applies to all Amazon CloudFront distributions.

and for S3 bucket,

> Individual Amazon S3 objects can range in size from a minimum of 0 bytes to a maximum of 5 TB. The largest object that can be uploaded in a single PUT is 5 GB. For objects larger than 100 MB, customers should consider using the multipart upload capability.

You can leverage the multipart upload feature of S3 to allow users to upload large files as profile pictures on your website. 
Please see this as reference 
https://aws.amazon.com/blogs/compute/uploading-large-objects-to-amazon-s3-using-multipart-upload-and-transfer-acceleration/
 You can split the large file into chunks of 5-10 MB, and upload each chunk  using multipart upload API.
At the end of all part upload, complete the multipart upload by combining the parts into a single object in S3.
