I was trying to use the project ShippingTesting in Visual Studio(C#). I tried UPS which works great.
But when I tried FeDex, it threw an error saying:
"Newtonsoft.Json.JsonSerializationException", " Additional information: Error converting value "PRE_TRANSIT" to type 'Shippo.ShippoEnums+TrackingStatus'. Path 'tracking_history[0].status',"
It looks like a JSON serialization issue. Will this be a constant issue with Fedex?
Thanks!
'PRE_TRANSIT' was added as a possible status in the latest version of the API (it replaces the older initial 'UNKNOWN' status for when a label has been created but has not yet entered transit).
The C# library may need to be updated to support this additional mapping. As a workaround, you can pass an older API version in the header of your request (pre '2018-02-08') and this should return the old 'UNKNOWN' mapping.
