ApiException{error=class ApiError { status: 500 errorCode: 904 message: Unable To Process errorType: internal pspReference: 851609774711826A invalidFields: null }

Test card:

Hello, this was a temporary issue with our TEST environment APIs which was resolved shortly after.
Attempting the same payment again should result in a successful auth.
