External Users Cannot See Custom WebParts Without CDN

Question

Hello,

We have developed custom WebParts in our SharePoint environment, but external users are unable to see them. We want to avoid using a CDN to grant them access to the assets.

Could you provide guidance on how to properly configure permissions or any alternative approach that would allow external users to view the WebParts without relying on a CDN?

Thank you for your support.

Best regards.

Hi @Rodrigo Meira,

You have to permissions to All Users(membership) on app catalog site where your SPFx solution is deployed.

Follow below steps:

1. Turn ON external sharing for your M365 tenant.
2. Download & open SharePoint Online Management Shell and run below commands using administrator account:

      Connect-SPOService -Url https://<tenant>-admin.sharepoint.com
      Set-SPOTenant -ShowAllUsersClaim $true
   

3. Grant "Read" permissions to All Users(membership) group on App Catalog (https://<tenant>-admin.sharepoint.com/sites/AppCatalogSite/_layouts/user.aspx) or on "Client Side Assets" library (https://<tenant>-admin.sharepoint.com/sites/AppCatalogSite/ClientSideAssets/AllItems.aspx) in App Catalog site as shown below:
