Test payment is cancelled S6011/P/78UVN

Hi. I’m trying to integrate payments to my application and faced problem with test payments. After payment method selection screen and autentication with fingerprint error message dialogue “Server error” appear with this error code - S6011/P/78UVN. Could someone help me understand what is the error? I found no description over the internet.
Interesting thing is that real payment works.
Thanks.

I saw this mentioned before. I think you need to bring this up as a Developer Request In the back of my head I remember something about this but it’s too vague to remember what it was.
