[itmsenior]

Preconditions (*)

1. Magento 2.3.5-p2
2. MSI 1.1.5

Steps to reproduce (*)

1. Create simple product in admin with manage_stock = 1
2. Order product
3. Attempt to ship order via shipment API (salesShipOrderV1)

Expected result (*)

1. Shipment is created

Actual result (*)

1. Shipment is not created with the following error shown: Could not save a shipment, see error log for details
   Error log shows the following:
   main.CRITICAL: The shipment couldn't be saved. {"exception":"[object] (Magento\\Framework\\Exception\\CouldNotSaveException(code: 0): The shipment couldn't be saved. at http/vendor/magento/module-sales/Model/Order/ShipmentRepository.php:150, Magento\\Framework\\Exception\\NoSuchEntityException(code: 0): Source item not found by source code: string and sku: 101308. at http/vendor/magento/module-inventory-source-deduction-api/Model/GetSourceItemBySourceCodeAndSku.php:59)"} []

Note: Shipping the order in Magento admin works fine, only when shipping via the API does this error occur.
