Invalid Type : <item code> of type: Item
Invalid Type: Item of type Inventory cannot be changed to Service item type
Applies to: ConnectWise, QuickBooks Online
How can this happen?
The item in error has been set as Inventory Type in QBO, which Wise-sync does not have the ability to create/update in QBO.
Either rename the item in QBO (add _old for example) to create a new item in QBO or if there are no transactions created yet for this item in QBO, and still possible to change the item type, then change it to Service type.
