Hi guys,
reading Microsoft Docs SharePoint Development overview, I found a nice querystring parameter, really helpful when trying to debug issues related to web parts placed on the page: ?maintenancemode=true

Using this querystring parameter, you can find a Web part summary, Web part manifest and Web part data.
In the WebPart manifest tab you can find valuable informations if you are trying to figure out possible problems with a WebPart like:

  • what version of the SharePoint Framework has the web part been built on
  • which components of the SharePoint Framework does the web part use

Normal page view

Maintenance mode page view using ?maintenancemode=true

Here you can find full article from Microsoft Docs SharePoint

Hope it is useful 🙂
