Yii2 - Logging 500 errors on production - php

Question

Im trying to debug an Internal Server Error on production that runs Yii2.
To do this, I added EmailTarget to my config file as follows
if(!YII_DEBUG){
$logTarget[] = [
'class' => 'yii\log\EmailTarget',
'mailer' =>'mailer',
'levels' => ['error'],
'message' => [
'from' => ['mail#example.com'],
'to' => ['mymail#example.com'],
'subject' => 'Log',
],
'categories' => [
'yii\db\*',
'yii\web\HttpException:*',
],
'except' => [
'yii\web\HttpException:404',
'yii\web\HttpException:403',
'yii\web\HttpException:401'
]
];
}
then
'log' => [
'traceLevel' => 3,
'targets' => $logTarget,
],
Im not getting the 500 errors though. Am I doing smt wrong? Or are 500 errors not logged by default

Answer 1

So finally got it working.
Apparently, the 'categories' here blocked 500 errors from being sent probably since most 500 errors belong to yii\base\Excetion and not yii\web\HttpException.
Since, by default, if no 'categories' are put, all the errors are included, just removing this from the array fixed the problem.
My fixed array is:
if(!YII_DEBUG){
$logTarget[] = [
'class' => 'yii\log\EmailTarget',
'mailer' =>'mailer',
'levels' => ['error'],
'message' => [
'from' => ['mail#example.com'],
'to' => ['mymail#example.com'],
'subject' => 'Log',
],
'except' => [
'yii\web\HttpException:404',
'yii\web\HttpException:403',
'yii\web\HttpException:401'
]
];
}
