Answer 1

In composer.json add this:

  "autoload"    : {
"classmap": [
  "database/seeds",
  "database/factories"
],
"files"   : [

  "app/GeneralModel.php" // <----------- ADD THIS 
],
"psr-4"   : {
  "App\\": "app/"
}},

Then run composer dump-autoload

Please check the GeneralModel.php in app folder. And execute the below command in your project root path.

php artisan dump-autoload
