System.MissingMethodException: 'Method not found: 'System.Threading.Tasks.Task`1<System.Net.Http.HttpResponseMessage> Flurl.Http.GeneratedExtensions.PostJsonAsync(Flurl.Http.IFlurlRequest, System.Object, System.Threading.CancellationToken, System.Net.Http.HttpCompletionOption)'.' about vendr-payment-provider-quickpay HOT 3 OPEN

Hi @ClausTS

I guess this is failing when going to payments from checkout, which make a POST request to /payments endpoint: https://learn.quickpay.net/tech-talk/api/services/#POST-payments---format-

If you have a fork of the repository locally and debugging on this, could you try to set a breakpoint it the catch block and continue execution of the code. I think you should be able to see a detailed error response from QuickPay then.

Hi @bjarnef,

thank you for your quick reply. I think we're misunderstanding eachother, so I'll try to elaborate - perhaps my explanation is the failing part. 😊

I don't get to the catch of the FlurlHttpException, it's the func.Invoke(req) above that fails.

I have a screenshot from the QuickPayCheckoutPaymentProvider.cs file, that perhaps can help.

The problem arises in line 119, and is then caught on line 145, with the errormessage from subject.

Okay, then I believe that you in the catch block here https://github.com/vendrcontrib/vendr-payment-provider-quickpay/blob/v2/dev/src/Vendr.Contrib.PaymentProviders.QuickPay/QuickPayCheckoutPaymentProvider.cs#L145 should be able to see an detailed error message.

If not you could try grabbing the JSON from the Flurl request and try a manually POST via e.g. Postman.
