Currency Error if you remove [optional] currency parameter.

[jayxd-com]

I don't have permission to update branch so let me give you the solution here.

Solution:
There was an error if we don't use optional currency in controller. It was under displayRedirectionPage function in PayfortRedirectRequest trait. Amount parameter was expecting a value from that array. I have updated the trait function by using laravel data_get as used for currency attribute.

Update the following parameter currency as follows.

// Traits/PayfortRedirectRequest.php

public function displayRedirectionPage($data)
{
//Other Parameters

  'amount' => $this->getPayfortAmount($data['amount'], data_get($data, 'currency', $this->config['currency'])),

//Other Parameters
}

Please update the repository, Thank you. Great work by the way.
