'There was an error uploading your item to the Gallery'

Hello, I recently had this after updating to the current patch. I tried something out and it worked for me! Hope it helps anyone else with this issue! 😊

The lot I was trying upload to the gallery, and got the error message with, was already saved in my library. So I entered into the lot in build mode and then resaved it to my library and I was able to upload it to the gallery with out any error message.
