Error Messages:
laravel which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

Solution:

To turn off strict mode.
Modify the MySQL parameter in the app/database.php file with the following changes.

'mysql' => [
	'driver' => 'mysql',
	'host' => env('DB_HOST', '127.0.0.1'),
	'port' => env('DB_PORT', '3306'),
	'database' => env('DB_DATABASE', 'forge'),
	'username' => env('DB_USERNAME', 'forge'),
	'password' => env('DB_PASSWORD', ''),
	'unix_socket' => env('DB_SOCKET', ''),
	'charset' => 'utf8mb4',
	'collation' => 'utf8mb4_unicode_ci',
	'prefix' => '',
	'strict' => false, //Important
	'engine' => null,
],
