Solution: Enable Custom Script!
To enable custom script in SharePoint Online, do the following:
- Sign in to Your SharePoint Online Admin Center site: https://YourDomain-Admin.SharePoint.com
- Click on Settings from the left navigation >> Scroll down to the “Custom Script” section
- Under the Custom Script section, Set “Allow users to run custom script on personal site” and “Allow users to run custom script on self-service created sites” options to enable custom script SharePoint online.
- Click on “OK” to save your changes.
However, this change may take up to 24 hours to reflect. To enable custom script on a particular site collection immediately, use this PowerShell script through SharePoint Online Management Shell.
