Script editor web part for modern pages

Contributor(s)

What happened?

Script Editor no longer works as expected. Started 1st July.

Script manager displays blank gaps in page where there would be the result of the javascript editor. When you edit the page, the webpart does not load correctly, and when you configure the part, the error message

"No settings available. The web part or dashboard card using this property pane was deleted."

Cannot add the editor again, as it is no longer displaying in the list of webparts to add. However in the application catalog the webpart is still showing as added and enabled

Steps to reproduce

1. Load webpage that has modern web editor added
2. Click on edit page
3. Select webpart and click the pencil icon

Expected behavior

On edit page, I expect to see the heading of Modern Javascript editor, and be able to configure the javascript when clicking the pencil icon

Microsoft has updated its settings related to custom scripts. From now on, custom scripts will only remain active for 24 hours. When you activate this feature, the custom script will be available again, but only for a 24-hour ...

I've tried using Powershell but it still disables after 24 hours. Does anyone know of a way to make it retain the setting?

[gdelgiovine]

What version are you using? The one that allow to load the script from URL?

You should be able to prevent the 24 hour reset by using:

Set-SPOTenant -DelayDenyAddAndCustomizePagesEnforcement $True

This will stop working from November 2024
