Laravel 5.5 application not booting anymore with "A facade root has not been set."

Question

For some reason one of our applications isn't booting anymore. The stack trace looks like this:

PHP Fatal error:  Uncaught RuntimeException: A facade root has not been set. in /app/vendor/laravel/framework/src/Illuminate/Support/Facades/Facade.php:218
Stack trace:
#0 /app/app/Exceptions/Handler.php(43): Illuminate\Support\Facades\Facade::__callStatic('get', Array)
#1 /app/vendor/laravel/framework/src/Illuminate/Foundation/Console/Kernel.php(352): App\Exceptions\Handler->report(Object(Dotenv\Exception\InvalidFileException))
#2 /app/vendor/laravel/framework/src/Illuminate/Foundation/Console/Kernel.php(123): Illuminate\Foundation\Console\Kernel->reportException(Object(Dotenv\Exception\InvalidFileException))
#3 /app/artisan(37): Illuminate\Foundation\Console\Kernel->handle(Object(Symfony\Component\Console\Input\ArgvInput), Object(Symfony\Component\Console\Output\ConsoleOutput))
#4 {main}
  thrown in /app/vendor/laravel/framework/src/Illuminate/Support/Facades/Facade.php on line 218

I'm sure there's something that changed and stopped the application from booting. But I have no clue what exactly happened. Any help is greatly appreciated.

Was there any custom Facade created recently for which `getFacadeAccessor` is not properly configured in facade class? maybe comment each custom facade one by one and then see which one is the culprit? — Mihir Bhende, Feb 12 '19 at 22:22
`Illuminate/Support/Facades/Facade.php` will be the file where you can see if it can not instantiate the class using `getFacadeRoot`, it throws that error — Mihir Bhende, Feb 12 '19 at 22:25
Thanks for the suggestion, I'm not quite sure how I would find the culprit from within the `getFacadeRoot` method. — Daniel Becker, Feb 12 '19 at 22:34

As a sanity check, completely delete your vendor directory and then re-install (or update) your dependencies. It is possible a file in there was mistakenly changed and is now causing problems.

rm -rf vendor
composer update

The solution was quiet simple but difficult to find.

.env variables should not be assigned as KEY="VALUE" and also too many spaces can crash the initialisation of the .env

i.e: DB_HOST= mysql

Just correct the .env and it should work like a charme
