So I think I know why it was triggering the VendorTxCode error – whenever I try to make a booking, I get the red “because of a technical error” message. So I refreshed the page and tried the same booking again. This triggered the TxCode error.
I just tried another booking, got the red technical error, but instead of refreshing I went back to start the booking again from scratch.
From the logs I can see the transactions are being added with unique txn codes, but nothing’s going through – Im just seeing the red technical error message.
