No Application Encryption Key Has Been Specified
From Encryption - Laravel - The PHP Framework For Web Artisans:
"Before using Laravel's encrypter, you must set a key option in yourconfig/app.php configuration file. You should use the
php artisan key:generatecommand to generate this key"
I found that using this complex internet query in google.com:
"laravel add encrption key" (Yes, it worked even with the typo!)
Note that if the .env file contains the key but you are still getting an application key error, then run php artisan config:cache to clear and reset the config.
In my case, I also needed to reset the cached config files:
php artisan key:generatephp artisan config:cache
Open command prompt in the root folder of your project and run below command:
php artisan key:generateIt will generate Application Key for your application.
You can find the generated application key(APP_KEY) in .env file.
