Device & OS: not provided
Scenario: Configuring the SharePoint Stream web part on a site page to display a collection of videos sourced from a specific folder.
Observed behavior: The Stream web part successfully displays individual videos and playlists, but it throws an error specifically when the Folder source option is selected, regardless of whether the folder contains videos.

Solution 1Recommended

Create a Video Library using SharePoint Classic Experience

Creating a media-specific library through the SharePoint classic experience often provides the necessary indexing and structure required by the Stream web part to read folder sources properly.

The Folder source option in the Stream web part can sometimes fail when linked to standard modern document libraries. Re-creating the library as a specific Document or Video library within the classic experience resolves the underlying compatibility issue.

Navigate to Site Contents

Open your SharePoint site, click on the Settings gear icon in the top right corner, and select 'Site contents'.

Add a New App

From the Site contents page, click on 'New' or go directly to Settings and choose 'Add an app'.

Switch to Classic Experience

Look for and click on the 'classic experience' link on the Apps page to access legacy library templates.

Create the Library

Select the option to create a 'Document Library' or 'Video Library', give it a recognizable name, and complete the creation process.

Upload and Link Videos

Open the newly created library, upload your video files, and then return to your Stream web part. Choose the 'Folder' option again and select this new library as the source.

Persistent Errors: If the error continues after applying this fix, check your library's permission settings to ensure the Stream web part is not being blocked from accessing the folder contents.

Frequently Asked Questions

Why does the SharePoint Stream web part work for single videos but not folders?

The Folder source option requires specific metadata and indexing structures to load multiple items simultaneously. Standard modern document libraries sometimes lack the specific configurations that classic video libraries provide out-of-the-box, triggering the error.

Where can I find the 'classic experience' link in modern SharePoint?

You can access the classic experience by going to Site contents, clicking on 'New', selecting 'App', and then looking for the 'classic experience' text link usually located near the top or bottom of the modern Apps page.

Can I convert an existing document library into a classic video library?

No, you cannot directly convert a standard modern document library into a classic video library. You must create a new library using the classic experience template and move your video files to the new location.
