Sandbox > Pull Transaction Errors

Hello team TabaPay,

We're seeing errors when doing pull transactions in Sandbox against test cards and are not sure why.

    "transactionID": "Ch0IGZsUCUPT-A5VO1-gGA",  
    "network": "MasterCard",

}

Any clues would be great help.

Btw, we're using test cards from here: https://developers.tabapay.com/reference/sandbox-test-cases-and-cards, a lot of which are failing in usage.

Thanks!
