Laravel facade problem when deployed on aws lambda - php

Question

I'm using laravel 8 and bref to deploy it on lambda. After making a cron job function to send email. When I deploy it, there's a problem with the facade
{
"errorType": "RuntimeException",
"errorMessage": "A facade root has not been set.",
"stackTrace": [
"#0 /var/task/app/functions/sendTestMail.php(11): Illuminate\\Support\\Facades\\Facade::__callStatic()",
"#1 /var/task/vendor/bref/bref/src/Runtime/Invoker.php(34): Bref\\Runtime\\FileHandlerLocator->App\\Functions\\{closure}()",
"#2 /var/task/vendor/bref/bref/src/Runtime/LambdaRuntime.php(102): Bref\\Runtime\\Invoker->invoke()",
"#3 /opt/bref/bootstrap.php(43): Bref\\Runtime\\LambdaRuntime->processNextEvent()",
"#4 {main}"
]
}
here is my directory structure and the function:
sendTestMail.php
serverless.yml:
service: test
provider:
name: aws
# The AWS region in which to deploy (us-east-1 is the default)
region: ap-southeast-1
# The stage of the application, e.g. dev, production, staging… ('dev' is the default)
stage: dev
runtime: provided.al2
package:
# Directories to exclude from deployment
exclude:
- node_modules/**
- public/storage
- resources/assets/**
- storage/**
- tests/**
functions:
# This function runs the Laravel website/API
web:
handler: public/index.php
timeout: 28 # in seconds (API Gateway has a timeout of 29 seconds)
layers:
- ${bref:layer.php-80-fpm}
events:
- httpApi: "*"
# This function lets us run artisan commands in Lambda
artisan:
handler: artisan
timeout: 120 # in seconds
layers:
- ${bref:layer.php-80} # PHP
- ${bref:layer.console} # The "console" layer
cron:
handler: app/functions/sendTestMail.php
layers:
- ${bref:layer.php-80}
events:
- schedule: rate(5 minutes)
plugins:
# We need to include the Bref plugin
- ./vendor/bref/bref
Anyone know how to resolve this issue? And btw, how can I test a handler function on my local machine before deploying? Thank you

Answer 1

I believe this is due to the issue that in your web function the handler is public/index.php. This properly initializes the Laravel application. Your cron functions handler is app/functions/sendTestMail.php so index.php never gets called and the Laravel kernel never handles the request.
I don't have a great solution at the moment because I feel like it is breaking a lot of best practices and rules in Laravel and want to experiment more with it. But I was able to take the entire index.php content and pasted it above my return function in the file that Lambda was calling.
So in other words I think if you paste this
use Illuminate\Contracts\Http\Kernel;
use Illuminate\Http\Request;
use App\Models\Task;
define('LARAVEL_START', microtime(true));
if (file_exists(__DIR__.'/storage/framework/maintenance.php')) {
require __DIR__.'/storage/framework/maintenance.php';
}
require __DIR__.'/vendor/autoload.php';
$app = require_once __DIR__.'/bootstrap/app.php';
$kernel = $app->make(Kernel::class);
$response = tap($kernel->handle(
$request = Request::capture()
))->send();
$kernel->terminate($request, $response);
As the first thing in your app/functions/sendTestMail.php file, it will likely work. Depending on what you have coded in your Middleware as that will run first.
This worked for me in my application.

You can try this for the error
php artisan config:cache
php artisan config:clear
php artisan cache:clear
