A number of our users may experience issues with downloading orders from eBay. This may occur due to a change in eBay's Global Shipping Program orders, in which the order information would be transmitted incorrectly to Linnworks, returning the following error message: "Error converting transaction ********* Error:Object reference not set to an instance of an object."
We have raised this issue on eBay and were informed that a fix for this is currently being developed on their end, however, no ETA has been provided on when this will actually be released. As such, we are currently looking into ways to prevent this error from affecting all orders which may not be experiencing the same issue on eBay.
A temporary workaround for this issue would be to process the corrupted GSP orders directly on eBay and running another synchronization procedure, which will then download all orders that were missed previously.
