Dataflow Gen 2 destination setup to SharePoint List

[Sandra_h710]

Hi Support Team,

I’m trying to set up a data destination connection with a SharePoint List. I’ve attempted using the following https:// connection strings:

• xxxxx.sharepoint.com/sites/xxxInsights/Lists

• xxxxx.sharepoint.com/sites/xxxInsights

However, both result in the same system exception. Below is the error message:
An exception occurred: Expression.Error: The column 'RootFolder' of the table wasn't found. (Session ID: acc75a8d-2acf-404b-904d-029759b9e0a6, Region: Australia).

Could you please advise what the correct connection string should be?

Thanks ~~

Hi @Sandra_h710,

Thank you for posting your query in Microsoft Fabric Community Forum.

The error you are seeing The column 'RootFolder' of the table was not found usually happens when trying to connect to a SharePoint List using an incorrect URL or connector. It looks like the connection string you are using might be targeting the SharePoint folder structure instead of the list itself.

To fix this, please make sure you are using the SharePoint Online List connector and not the SharePoint Folder or Web connector. Avoid adding /Lists/YourListName to the end that part is only for navigation in the browser, not for data connection purposes. Once you connect, you will see a list of available SharePoint Lists in the navigator. From there, you can pick the one you need and proceed with transforming or loading your data.

For step-by-step instructions and supported behaviour across tools like Power BI or Dataflow Gen2, here’s the official Microsoft documentation you might find helpful:

Hope this helps clarify things and let me know what you find after giving these steps a try happy to help you investigate this further.

Thank you for using the Microsoft Community Forum.
