Invalid config file format

app/config/rave.php

/**

 * Public Key: Your Rave publicKey. Sign up on https://rave.flutterwave.com/ to get one from your settings page
 *
 */
'publicKey' => env('RAVE_PUBLIC_KEY'),
/**
 * Secret Key: Your Rave secretKey. Sign up on https://rave.flutterwave.com/ to get one from your settings page
 *
 */
'secretKey' => env('RAVE_SECRET_KEY'),

But it should be,

return [

/**
 * Public Key: Your Rave publicKey. Sign up on https://rave.flutterwave.com/ to get one from your settings page
 *
 */
'publicKey' => env('RAVE_PUBLIC_KEY', 'FLWPUBK-xxxxxxxxx-X'),

/**
 * Secret Key: Your Rave secretKey. Sign up on https://rave.flutterwave.com/ to get one from your settings page
 *
 */
'secretKey' => env('RAVE_SECRET_KEY','FLWSECK-xxxxxxx-X'),

Otherwise you will have an undefined public key and secret.
