In my case, the problem was 'supportsEMV' .I just removed 'supportsEMV'
from merchantCapabilities and it worked.When this is included, VISA
cards are working fine, but others give the error "Required fields are
missing from decrypted data".
Hi! We are having the same issue where Visa is working but AMEX and
MasterCard is coming back with the error "There was an error processing
the payment data. Required fields are missing from decrypted data."Did
you resove this issue?Ugur.
