Errors do not appear on cloudwatch logs

[Maxlegend87]

Description:
I'm trying bref to make a little PHP application, so far I'm loving it!

But when throwing an error, I can't find the error in the cloudwatch logs:

INIT_START Runtime Version: provided:al2.v24	Runtime Version ARN: arn:aws:lambda:eu-west-1::runtime:81d6fc3f612653d45ec654b442cabc69425b90001d6194d931e501a2c7bc7bb3

And I couldn't find anything to fix it.

How to reproduce:

    }
}

src/index.php:

<?php
throw new Exception('Division by zero.');
echo "Hello";
?>

PHP-FPM behaves like on any server: exceptions are not automatically logged.

You need to use an error handler (or a framework that automatically has that feature), see here for more info: #1550 (comment)

Thanks!
Once adding log_errors = on to the php.ini it started logging correctly logging the errors.
I would suggest to add this to the documentation if possible.

Have a nice day!
