Android CRUD Volley + Symfony API Platform - how debug errors?

Hello,

I develop for Android in the android studio and make a CRUD application using Volley for HTTP requests. I send data to PHP Symfony with API Platform. In the android studio, the error http 400 and http 500 is often seen in the debug. I can't simply list the response responses in the CRUD application simply in php, and I don't know how to debug it properly. Authorization via the header with 'X-AUTH-TOKEN' is 100% OK. Can anyone please advise what to do with it? Thanks

Hello,

I debug such API requests via log in Symfony - I will give the command in Linux tail /var/www/app7/var/log/dev.log

The log will then show you specific errors from the API platforms:
