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.

403 This action is unauthorizedLaravel

Laravel: Illuminate\Auth\Access\AuthorizationException: This action is unauthorized.

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

429 Too Many Requests (Laravel throttle)Laravel

Laravel: Illuminate\Http\Exceptions\ThrottleRequestsException: Too Many Attempts. / 429 Too Many Requests

Laravel's rate limiter blocked the client for exceeding the allowed requests per minute.

Sanctum: 401 UnauthenticatedLaravel

Laravel Sanctum: {"message":"Unauthenticated."} 401 on API / SPA requests

A request to a `auth:sanctum` route had no valid token or session, so Laravel returned 401.

422 Unprocessable Entity: The given data was invalidLaravel

Laravel: {"message":"The given data was invalid.","errors":{"email":["The email field is required."]}} (422)

Request validation failed, so Laravel returned HTTP 422 with the field errors.

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.

Attempt to read property "x" on nullLaravel

Laravel/PHP 8: ErrorException: Attempt to read property "name" on null

You accessed a property on a value that is `null`, typically an empty relationship or a query that found nothing.

Two steps away (21)

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).

Target class does not existPHP

Laravel: Target class [App\Http\Controllers\X] does not exist.

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

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.

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.

421 4.7.0 Try again later (rate limited)Email / SMTP

SMTP: 421 4.7.0 Our system has detected an unusual rate of unsolicited mail originating from your IP address. Mail sent from your IP address has been temporarily rate limited

The receiving server (often Gmail or Outlook) is temporarily throttling your mail because the volume or reputation of your sendin…

SES: Maximum sending rate exceededEmail / SMTP

Amazon SES: Throttling — Maximum sending rate exceeded (454 Throttling failure)

You are sending faster than your Amazon SES account's per-second limit, so SES throttles the requests.

invalid csrf tokenAuthentication

ForbiddenError: invalid csrf token (EBADCSRFTOKEN)

The request’s CSRF token is missing or doesn’t match the token tied to the user’s session/cookie.

Session store not set on requestLaravel

Laravel: RuntimeException: Session store not set on request

Code used `session()` or `$request->session()` in a route/middleware group that doesn't run the session middleware.

Token has expired (tymon/jwt-auth)Laravel

Laravel JWT: Tymon\JWTAuth\Exceptions\TokenExpiredException: Token has expired / The token could not be parsed from the request

A JWT sent by the client is expired, invalid or absent, so `jwt-auth` rejects the request.

1406MySQL

MySQL ERROR 1406: Data too long for column

The value is longer than the column allows (e.g. 300 characters into VARCHAR(255)), and strict mode rejects it instead of truncat…

1048MySQL

MySQL ERROR 1048 (23000): Column 'x' cannot be null

An INSERT/UPDATE put NULL into a NOT NULL column.

1264MySQL

MySQL ERROR 1264 (22003): Out of range value for column 'x' at row 1

A number is too large (or negative for UNSIGNED) for the column type.

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.

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.

Vite manifest not foundPHP

Laravel: Vite manifest not found at: public/build/manifest.json

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

Laravel: Expected response code 250 but got 550Email / SMTP

Laravel: Expected response code "250" but got code "550", with message "550 5.7.1 Relaying denied"

Laravel connected and authenticated but the SMTP server rejected the message at the RCPT TO / MAIL FROM / DATA step with the code…

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.

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.
