{"errors":[{"errorId":30500,"domain":"API_FULFILLMENT","category":"APPLICATION","message":"System error."},{"errorId":30500,"domain":"API_FULFILLMENT","category":"APPLICATION","message":"System error."}]}
I get the above the last couple days. Nothing has changed on our programming for the past 2 months and has been working well before Christmas. I have checked the Fulfilment API document and don't seems to find anything new that trigger the error. Please help.
Thank you.
