StreamHandler class not found when logging deprecation warnings

[smknstd]

• Laravel Version: 8.80
• PHP Version: 8.1
• Database Driver & Version: mysql 8

Description:

When trying to use deprecation logging feature, some of my endpoint crashes with error 500 and nothing is catched in laravel's logs. I found this in /var/log/nginx/myproject-error.log :

[error] 815505#815505: *1186160 FastCGI sent in stderr: "PHP message: PHP Fatal error:  Uncaught Error: Class "Monolog\Handler\StreamHandler" not found in /home/forge/myproject/vendor/laravel/framework/src/Illuminate/Log/LogManager.php:175

It looks pretty similar to #39938

Steps To Reproduce:

in config/logging.php :

'deprecations' => env('LOG_DEPRECATIONS_CHANNEL', 'null'),

'channels' => [
        ...
        'php_deprecation_warnings' => [
            'driver' => 'single',
            'path' => storage_path('logs/php-deprecation-warnings.log'),
        ],
]

in .env :

LOG_DEPRECATIONS_CHANNEL=php_deprecation_warnings

@smknstd I will need you to send me the full error output.

[smknstd]

Hello @nunomaduro ! This is all I got unfortunately it seems truncated or something in nginx logs for some reason ...

[nunomaduro]

Are you running the latest version of monolog? Do you mind upgrading that package?

[smknstd]

I think it is the last version. From composer lock:

        {
            "name": "monolog/monolog",
            "version": "2.3.5",

I encountered the same error in our staging environment this morning after upgrading to framework version v8.83.1.
Could not get it to trigger locally though.

Rolling back to v8.83.0 did not solve it though.

monolog versions: 2.3.5

We use LOG_DEPRECATIONS_CHANNEL=stderr

@smknstd Do you have Sentry or some other exception handling service?
Trying to guess if that has any effect

[smknstd]

Great point ! Yes, we have getsentry/sentry-laravel 2.11.0

[nunomaduro]

Can you share the full "logging.php" file?

[hmazter]

This is our config/logging.php

<?php

use Monolog\Handler\StreamHandler;

return [
    'default' => env('LOG_CHANNEL', 'stderr'),

    'deprecations' => env('LOG_DEPRECATIONS_CHANNEL', 'stderr'),

    'channels' => [
        // Should  be used for docker
        'stderr' => [
            'driver' => 'monolog',
            'handler' => StreamHandler::class,
            'formatter' => env('LOG_STDERR_FORMATTER'),
            'tap' => [
                \App\Logging\AddAmznTraceIdContext::class,
                \App\Logging\AddRecruiterIdContext::class,
            ],
            'level' => env('LOG_LEVEL', 'debug'),
            'with' => [
                'stream' => 'php://stderr',
            ],
        ],
    ],
];

[nunomaduro]

@hmazter Can't reproduce your issue. But aren't you missing an emergency channel there?

https://github.com/laravel/laravel/blob/4a6229aa654faae58f8ea627f4b771351692508c/config/logging.php#L114

[driesvints]

I'd also recommend against modifying the logging.php file like that. It's best that you leave the defaults in place.

[hmazter]

There was no emergency when we created the app back in Laravel 6.
And it has worked, probably since the emergency logger has a fallback in the code

framework/src/Illuminate/Log/LogManager.php

Lines 173 to 178 in 7ba34a8

	$config = $this->configurationFor('emergency');
	$handler = new StreamHandler(
	$config['path'] ?? $this->app->storagePath().'/logs/laravel.log',
	$this->level(['level' => 'debug'])
	);
