Hi ,  made a automated process where my store orders are fulfill when the trackingnumbers are ready , everything was working fine until a couple of days ago where most of the orders started to failed this process , now im getting status 422 Unprocessable Entity , 


my url : 



im testing this on POSTMAN and added my basic auth info there , which still works fine for other calls

and i get this response :

    "errors": {
        "base": [
            "An error occurred, please try again"
this is the call that im trying to do :
{"fulfillment":{"location_id":14716272703,"tracking_company":"FedEx","tracking_number":"9400111899562139715951","line_items":[{"id":4773907431487},{"id":4773907464255}],"notify_customer": true}}
i have verified that all the ids on the JSON and are valid , and this same automated process was working fine for every order until some couple days ago , any other calls are still working fine , only fulfill is throwing errors for me 
any help here would be very apreciated

Hey @AlfredoCalderon 


Do you have a request ID handy?
