Unsupported driver [file].

I am facing the issue of the unsupported driver while hitting my API I have the following configurations in my config/database.php

<?php

use Illuminate\Support\Str;

return [

	/*

	| Default Database Connection Name
	|--------------------------------------------------------------------------
	|
	| Here you may specify which of the database connections below you wish
	| to use as your default connection for all database work. Of course
	| you may use many connections at once using the Database library.
	|
	*/

	'default' => env('DB_CONNECTION', 'mysql'),

	/*
	|--------------------------------------------------------------------------
	| Database Connections
	|--------------------------------------------------------------------------
	|
	| Here are each of the database connections set up for your application.
	| Of course, examples of configuring each database platform that is
	| supported by Laravel is shown below to make development simple.
	|

	| All database work in Laravel is done through the PHP PDO facilities
	| so make sure you have the driver for your particular database of
	| choice installed on your machine before you begin development.
