How to upload larger files to S3 using Bref and Lambda

[mslabba]

Hi,
I am using Bref for uploading my laravel application to AWS Lamba. Now the issue I am facing is I am unable to upload files more than 6MB to S3 in the application. Is there any option to increase the max upload size?

Hi, as explained in the docs you cannot upload more than 6MB to Lambda: https://bref.sh/docs/runtimes/http.html#binary-requests-and-responses

You'll have to upload directly to S3 (via presigned URLs) instead (no limit there).

Hi @mnapoli
Tried to setup presigned url in my bref project :
When the project is ran locally (on my own machine), the upload works (using my own aws access key)
But as soon I run it inside a lambda, the access key changes (starts with ASIA which refers to temporary keys), and the upload doesn't work anymore !

Any clue about how to setup presigned urls into bref ?

Just found the answer by myself:
When instanciating the S3 Client, instead of setting credentials (Secret + key), nothing must be provided. It seems the S3 client will then use the "current" IAM role, which just works !
