In App Provisioning PKErrorHTTPResponseStatusCodeKey=500

Hello, we are developing in app provisioning of our American Express network cards.

After clicking add to apple wallet in our app, I launch the PKAddPaymentPassViewController and click next.

It loads for a few seconds and then I get:

[<private>] ProvisioningOperationComposer: Step '<private>' failed with error Error Domain=PKProvisioningErrorDomain Code=5 UserInfo={PKErrorHTTPResponseStatusCodeKey=500}

Does anyone have any insight on what this error means?
