Shared folders are created, but the files are missing

[Dolphinsimon]

Describe the bug
We create shared folders by

Add-EflowVmSharedFolder -sharedFoldersJsonPath "C:\temp\sharedFolders.json"

The shared folders are created without errors, but the files and subfolders in the host folder are missing when we are trying to access them in the EFlowVM.

To Reproduce
Steps to reproduce the behavior:

1. Add-EflowVmSharedFolder -sharedFoldersJsonPath "C:\temp\sharedFolders.json"
2. Connect-EFlowVM, navigate to the shared path, the folder is empty.

Expected behavior
All files and subfolders in the host folder should be accessible in EFlowVM

Windows Host OS (please complete the following information):

• Edition: Windows10 Enterprise LTSC 2019
• Version: build 17763
• Virtual Machine: None

Additional context
We have tested the folder with:

 Get-EflowVmSharedFolder -sharedfolderRoot "C:\temp" -hostFolderPath @("iotedgegateway")
hostFolderPath readOnly targetFolderOnGuest hostFolderFullPath
-------------- -------- ------------------- ------------------
iotedgegateway    False /srv/IoTEdgeGateway C:\temp\iotedgegateway

The sharedfolder.json content:

[
    {
        "sharedFolderRoot": "C:\\temp",
        "sharedFolders": [
            {   
                "hostFolderPath": "iotedgegateway", 
                "readOnly": false, 
                "targetFolderOnGuest": "/srv/IoTEdgeGateway" 
            }
        ]
    }
]
