Laravel Errors

Important Points

For any new project, Laravel logs errors and exceptions in the App\Exceptions\Handler class, by default. They are then submitted back to the user for analysis.

When your Laravel application is set in debug mode, detailed error messages with stack traces will be shown on every error that occurs within your web application.

By default, debug mode is set to false and you can change it to true. This enables the user to track all errors with stack traces. .env file

The value is set to true in a local development environment and is set to false in a production environment.
If the value is set to true in a production environment, the risk of sharing sensitive information with the end users is higher.

File name : index.php


Error Log

The log information can be configured in the web application in config/app.php file.

The logging parameters used for error tracking are single, daily, syslog and errorlog.

File name : index.php

'log' => env('APP_LOG',’daily’),
‘log_max_files’ => 25;
'log_level' => env('APP_LOG_LEVEL', 'error')

File name : index.php

*/
public function boot()
{
//
Schema::defaultStringLength(191);

<meta name="csrf-token" content="{{ csrf_token() }}">

If show error after submitting the form then you need to add the CSRF field in your form.
<form method="POST" action="/profile">
@csrf
...
</form>


Condition Two:
If show error after calling the AJAX then you need to add a header like below.
In your head tag
<meta name="csrf-token" content="{{ csrf_token() }}">

In Your Script tag
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});

use Illuminate\Http\Request;
To

use Request;

add {{csrf_field}} to @csrf

then

add SESSION_DOMAIN= in your .env file

or in your config/session.php 'domain' => env('SESSION_DOMAIN', ''),

and then run php artisan cache:clear

case 2: if project is running on server and you have domain like "mydomain.com"

add SESSION_DOMAIN=mydomain.com in your .env file

or in your config/session.php 'domain' => env('SESSION_DOMAIN', 'mydomain.com'),

<!-- Equivalent for @csrf directive -->
<input type="hidden" name="_token" value="{{ csrf_token() }}">
