Update Parameters Error

[paulcorke]

Using the Android integration in the demo environment, contactless test card on a terminal with built in NFC. All transactions are getting declined with "(-12) TRANSACTION_DECLINED_BY_SERVER". I can't find anywhere in the portal or app which gives any more detail on why this might be happening. Is there somewhere I can look?

If I try to make a payment just using the Viva Demo app, I can make ONE successful payment (only) before it starts failing with the same declined error. It also shows a toast with "Update parameters error". I found an option in "Settings" to Update but it just gives the same error. If I use the "Settings Reset" option it looks like I can make one more successful payment before needing to reset again. A "Full Reset" seems to show the same behaviour.

What can I do to work out why this is happening?

Hello, the request is: vivapayclient://pay/v1?appId=com.scologic.posimple&action=sale&clientTransactionId=0226315870344&amount=1000&tipAmount=0&show_receipt=true&show_transaction_result=true&show_rating=true&ISV_amount=0&ISV_clientId=7t4047e6d4fn0s42zvu2wlsuooa17f5ivp2wk6scjixp5.apps.vivapayments.com&ISV_clientSecret=redacted&ISV_sourceCode=Default&ISV_currencyCode=826&ISV_customerTrns=POSimple&ISV_clientTransactionId=0-63-0226315870344&ISV_merchantId=501eb127-2340-4b5f-9b16-2968c60670f6&ISV_merchantSourceCode=63&paymentMethod=CardPresent&callback=posimplecb://result

I have redacted the ISV_clientSecret - I believe the value is correct as it is trying to process the transaction.

The application version is:

  v4.24.0(8152)
  06/07/2023, 08:16:31
  Demo Release

I have also re-sent logs following the above transaction attempt which was run just now (20230711 around 13:33 BST) and was declined.
