[backend] Request too large gets discarded without logging infos for debugging

Description

In our backends we have set a limit for the size of incoming json payload up to 10mb, but we don't log any useful info when the request is too large and gets rejected. So we're not able to investigate who's sending those requests and eventually spot a bug on our side.

Details

No response

Version

2.8.0

Steps to reproduce

There's no easy was to reproduce this at the moment, but at high level these should be the steps:

generate a json bigger than 10MB
generate a keypair for signing the request payload
sign the payload and use the signature in X-YTtrex-Signature header
use your pubKey in X-YTtrex-PublicKey header
send the request to POST /v1/events
