Hi guys,

I'm new to Power Apps. Would like to seek for helps regarding Azure Blob Storage connector with AAD authentication method.
I build a simple apps with refer to online materials with function of show the list of container as well as show list of files inside container selected with simple upload function. This works perfectly with using Access Key method.

As my requirement with security concerns, we would like to test out AAD authentication method. Thus I just remove the connection and change to AAD connection and my apps totally does not works.

Even with simple function to display list of files in specific container also not working.
My formula used as below
AzureBlobStorage.ListFolderV2("mycontainername").value

The error message show requires the storage account name to be non-empty. This authentication type only supports operations that take the storage account name as a required parameter.

I tried to research on this error message and not much information found.

Thanks in advance

Hi All,
I am also facing the same issue as mentioned here.
My requirement is to create an excel file into blob container and that excel file I am uploading it through attachement control on power app.
THrough a button click I am writing AzureBlobStorage.CreateFile().
But due to some security issue I had to switch connection of (Azure blob stoarage) to Azure AD integrated type.
I am seeing this error :
The error message show requires the storage account name to be non-empty.
This authentication type only supports operations that take the storage account name as a required parameter.
Any idea on this issue. Feel free to suggest.

Using AD authentication adds a difference in how the command has to be done. Try using:
AzureBlobStorage.ListRootFolderV4("mystorageaccountname").value
I couldn't get it to work in ListFolderV2 and had to use ListFoderV4 in order to make it work. I realize that you are listing folders. I ended up listing the root folder and then selecting a folder under that in a different gallery.

First gallery uses: AzureBlobStorage.ListRootFolderV4("mystorageaccountname").value

Second gallery uses: AzureBlobStorage.ListFolderV4("mystorageaccountname",Gallery1.Selected.Id).value

For me this works but both have to be used in V4 and not V2. I couldn't get either V2 to work.
