Laravel: Allowed memory size exhausted (request)Laravel

Laravel/PHP: Allowed memory size of 134217728 bytes exhausted (tried to allocate 20480 bytes) in vendor/laravel/framework

A request (or artisan job) used more memory than PHP's `memory_limit` allows.

A policy or gate denied the action for the current user, so Laravel returned HTTP 403.

Command "x" is not definedLaravel

Laravel: Symfony\Component\Console\Exception\CommandNotFoundException: Command "make:livewire" is not defined. Did you mean one of these?

`php artisan` doesn't know the command you typed — typo, missing package or an unregistered service provider.

BadMethodCallException: Call to undefined methodLaravel

Laravel: BadMethodCallException: Call to undefined method App\Models\Post::whereTitle() / Illuminate\Database\Eloquent\Builder::foo()

You called a method the model, builder or collection doesn't have.

ModelNotFoundException in queued jobLaravel

Laravel Queue: Illuminate\Queue\SerializesModels: No query results for model [App\Models\Order] 42 (job failed)

A queued job serialised a model by ID, but the record was deleted before the worker ran it.

No query results for modelLaravel

Laravel: Illuminate\Database\Eloquent\ModelNotFoundException: No query results for model [App\Models\Post] 5

`findOrFail`, `firstOrFail` or route-model binding couldn't find a record, so Laravel returns a 404.

Laravel’s container couldn’t find the controller or class named in a route or binding.

Code called route('name') for a route name that doesn’t exist — very often route('login') from the auth middleware in API-only ap…

The GET method is not supported for routeLaravel

Laravel: The GET method is not supported for route x. Supported methods: POST (MethodNotAllowedHttpException)

The URL exists, but not for the HTTP method used — e.g. opening a POST-only route in the browser, or a form sending GET.

Allowed memory size exhaustedPHP

PHP Fatal error: Allowed memory size of X bytes exhausted

The script tried to use more memory than PHP’s `memory_limit` allows.

SIGSEGVLinux

Segmentation fault (core dumped)

A program accessed memory it wasn’t allowed to, and the kernel killed it with SIGSEGV (exit code 139).

OOM killerLinux

Killed / Out of memory: Killed process (Linux OOM killer)

The kernel ran out of memory and killed a process to recover — the program just prints “Killed” (exit code 137).

Class "App\Models\X" not foundLaravel

Laravel: Error: Class "App\Models\Post" not found

PHP can't find the class you referenced — a missing import, wrong namespace or file name, or a stale autoloader.

Undefined variable $x (Blade view)Laravel

Laravel: ErrorException: Undefined variable $posts (View: /resources/views/posts/index.blade.php)

A Blade template uses a variable the controller didn't pass to the view.

Unable to locate factory for modelLaravel

Laravel: InvalidArgumentException: Unable to locate factory with name [default] [App\Models\Post] / Call to undefined method App\Models\Post::factory()

A seeder or test calls a model factory that is missing, or the model doesn't use the `HasFactory` trait.

No application encryption keyPHP

Laravel: No application encryption key has been specified.

Laravel’s APP_KEY is missing, so it can’t encrypt sessions and cookies.

419 Page ExpiredPHP

Laravel: 419 Page Expired (CSRF token mismatch)

Laravel rejected a POST because the CSRF token was missing, expired or didn’t match the session.

Laravel storagePHP

Laravel: The stream or file "storage/logs/laravel.log" could not be opened in append mode: Failed to open stream: Permission denied

The web server can’t write to Laravel’s storage or bootstrap/cache directories.

Laravel’s @vite directive can’t find the compiled asset manifest because assets weren’t built.

MaxAttemptsExceededException (queue job)Laravel

Laravel Queue: Illuminate\Queue\MaxAttemptsExceededException: App\Jobs\SendReport has been attempted too many times or run too long
