Cannot read properties of undefined (reading 'multichannel')

Question

Cannot read properties of undefined (reading 'multichannel')

Sabin Shrestha, BS, CCA 10

I created file storage in Azure, but when I connect to the file to access the script for mapping a drive to the user's computer, I encounter an error. I don't know what this means.

Hi Sabin Shrestha, BS, CCA ,

Could you provide more details about your setup and the specific part of the script where this error occurs?

This error typically occurs when the SMB client tries to establish multiple network connections to an SMB file share, but the configuration isn't set up correctly,

Ensure that SMB Multichannel is enabled and properly configured in your Azure file storage settings,

Make sure the client machine supports SMB 3.x, as SMB Multichannel requires this version,

Confirm that your network settings allow multiple connections and that there are no firewall rules blocking these connections.

I am having the same issue while running the Manage Azure Storage Lab for the AZ-104 labs that Microsoft publishes. This is occuring after the creation of the file share when you click the connect button in the file share settings to OBTAIN the script that you will run on the client to connect to the SMB share - NOT when the client is actually trying to connect to the share.

Hi Sabin Shrestha, BS, CCA,

There’s an Azure portal bug that affects Azure files when customers try to get the mounting script in the portal. Please find the details.

undefined

ISSUE

====================================

When customers click on “Connect” to get the mounting script for Azure files, they run into this error in the dialog box.

DETAILS & FIX

=======================================

This affects only some of the accounts and not all accounts.
This has been identified as a bug.
Fix will be deployed tomorrow.
Customers can use a private portal link to get the script for now -> https://ms.portal.azure.com/?feature.canmodifystamps=true&Microsoft_Azure_FileStorage=flight2#home
