IncorrectRowVersionSupplied - when doing bulk update

Hi,

We have started getting occasional IncorrectRowVersionSupplied errors while doing bulk updating an Inventory Item.

It seems like the inventory item RowVersion we get form /Inventory/Item API response is being rejected by the same API when we send it back in the update request.

 We are doing GET request first and using the response JSON we are updating the RowVersion in my put request.

This works fine when updating an Inventory but getting when doing the bulk inventory update
