When I try to ship an order that has the word "leash" in the SKU, this error message appears.
Source item not found by source code: default and sku:
All I can do is offline credit memo the order to change it from "Processing".
My store was migrated from a 1.9.0.1 installation. But it appears to only be SKUs with the word "leash" in them... all other skus seem to be working fine.
Thanks for taking the time to read/help!
