Pre-auth with Vault & CVD return error 476

Hi,

On debug mode (store5), I'm successfully able to add a credit card to the Vault.

 

As is seem that Vault do not validate CVD, I'm doing a pre-auth with Vault and CVD using the php script sample found at https://developer.moneris.com/Documentation/NA/E-Commerce%20Solutions/API/Pre-Authorization?lang=php.

 

I'm using the Visa 4242 test card. When doing the pre-auth (res_preauth_cc), I got a DECLINED message with responseCode=476 and IOS=12.

 

476 means "CREDIT CARD - Invalid transaction, rejected" but I canot found any document for the ISO 12 error code.

 

Where can I find more info to understand why it doesn't work?

 

Thanks
