This error is occur when this function is execute

Class "GuzzleHttp\Promise" not found

When this function is execute then payment link generate of that driver and should be instantly updated , Earlier This function is load too much time adn throw 504 timeout error that's why I have used Guzzle/http for fast response and reload because we have bulk of records.

1. Install the Missing Package Ensure you have installed the Guzzle HTTP library, which includes guzzlehttp/promises.

Run the following command in your Laravel project's root directory:

composer require guzzlehttp/guzzle

2. Verify that you're using the correct namespace for the Promise class in your code. For example:

   use GuzzleHttp\Promise\Promise;
