-    app:
-        handler: public/index.php
-        timeout: 8
-        layers:

+You need a new "bootstrap" file for AWS Lambda. That file should look like
+[this](https://github.com/brefphp/extra-php-extensions/blob/master/layers/symfony-runtime/bootstrap).

+[bref/extra-php-extension package](https://github.com/brefphp/extra-php-extensions).
