Generic error on checkout U0RLX0lOVEVHUkFUSU9OX0xPQURJTkdfRVJST1I

[jamanga]

Hi everyone

I have inherited a .NET PayPal implementation for our corporate website. I have a sandbox account utitlising API userbame/password/signature with an endpoint of https://api-3t.sandbox.paypal.com/nvp

Once the order details are passed to PayPal I see the url of sandbox.paypal.com and can log via my "buyer" sandbox account (which has funds). I select to pay the order but then if successful it should go to my "Success" page , but instead I just get this: https://www.sandbox.paypal.com/checkoutweb/genericError?code=U0RLX0lOVEVHUkFUSU9OX0xPQURJTkdfRVJST1I (and details of the cancel url). I noticed that U0RLX0lOVEVHUkFUSU9OX0xPQURJTkdfRVJST1I decodes back to SDK_INTEGRATION_LOADING_ERROR but can't find any details on what this might mean.

We reference these 2 .NET dlls:

PayPalCoreSDK.dll ver 1.6.0.0

PayPalMerchantSDK ver 2.13.117.0

.. which are functioning ok within the production PayPal environment i.e. non-sandbox

I look forward to any feedback, and please let me know if you need anymore details.

Hi everyone

Is there somewhere else/more active where I should have posted this question?

I added logging for each step - but I don't get further after my service.SetExpressCheckout request, where service is the PayPalAPIInterfaceServiceService object.

After logging in via my sandbox account (and confirming it's using the https://sandbox.paypal.com) 

I login with sandbox buyer details

-> select the payment and approve.

Then it *always* just says the error I've already mentioned with a "We're sorry something seems to have gone wrong" message, rather than redirecting to back to my Success page. This is really frustrating - I don't get any other info than this. Does anyone have any tips?
