I first noticed it yesterday, but it seems sometimes when doing refunds in production, we're receiving an E00051 error saying that "The original transaction was not issued for this payment profile."

However, when we try the same action again, the refund succeeds, so the issue is intermittent.

Captures of previous authorizations don't seem to be effected. It's only refunds where the intermittent error occurs, and since refunds have to be settled at Authorize.Net, it's a little difficult to track down.

I've contacted customer support, but is anyone else seeing this behavior, or have any ideas of what could cause it? We haven't made any recent changes to the payment processing part of our codebase. Thanks!
