Hi Saber,

I hope you are attach your lambda with API Gateway. The maximum data length to send via API Gateway 10MB also not good practice to send large amout via API Gateway. It will increase cost of AWS.

My suggestion is use "pre-signed url" concept.

If you want to upload files to s3 go with "pre-signed url". It is cost effective and good perofrmance than above approach. Also if you want to upload veey large file (like 100MB or more) than multipart upload (using pre-signed url) available.

https://docs.aws.amazon.com/AmazonS3/latest/userguide/ShareObjectPreSignedURL.html

1) Build lambda to create presigned url.
2) Call that lambda from client and get pre-signed url.
2) From the client upload file using pre-signed url.
