Paypal Sandbox API Internal Error

Question

I've been using Paypal Merchant SDK with Sandbox credentials for last few months and everything for working fine.

But today, Im facing this strange problem, whenever I make an API call of SetExpressCheckout, I get Transaction failed due to internal error with error code 10001 .. I haven't changed anything in code, it just started to show up.

Im using the github api for transaction: https://github.com/paypal/merchant-sdk-php/]1

Here is the API Error Response

SetExpressCheckoutResponseType Object

    [Token] =>

    [Ack] => Failure

        [0] => ErrorType Object
            (

                [ErrorCode] => 10001
                [SeverityCode] => Error
