We're getting resultErrorCode: E00027 with additional errorCode: 256 in
"createTransactionResponse"Is there any way to debug this and understand
the core reason behind this reponse?
It's just strange everything was working, and then it stopped working.
He did apply this patch (SUPEE-8967) around the same time, but said it
was done after the errors started happening. He did revert it just in
case, but it didn't fix the issue.
