System.MissingMethodException: Method not found Connect-PnPOnline

Using Visual Studio Code and SharePoint PNP I was trying to make some updates to a list but I wasn’t able to connect to a site.

Connect-PnPOnline -Url "https://taco.sharepoint.com/" -Credentials $creds

Error I was receiving:
System.MissingMethodException: Method not found: ‘System.Runtime.Remoting.ObjectHandle System.Activator.CreateInstance(System.String, System.String)’. at SharePointPnP.PowerShell.Commands.Base.ConnectOnline.ProcessRecord() at System.Management.Automation.CommandProcessor.ProcessRecord()

I tried uninstalling VScode, removed all traces of SharePoint from my laptop, and cleared the GAC. Nothing worked.

Here is what did work:
In VScode:

  1. Open the Command Palette on Windows or Linux with Ctrl+Shift+P. On macOS, use Cmd+Shift+P.
  2. Search for Session.
  3. Click on PowerShell: Show Session Menu.
  4. Choose one of the ___ (x86) options

Not sure how, but I was using an x64 session and SharePoint PNP clearly didn’t like that.

How to use an iFrame in a modern SharePoint Online page

Using the Embed web part I was trying to paste in a site URL when I should have been using the iFrame HTML tag.

example:

<iframe src="https://sharepointed.com" height="200" width="300"></iframe>

If you encounter this error: This website doesn’t support embedding using just the address ….

You will need to update the HTML Field Security settings in the Site Settings area of your site. In my case, I simply added sharepointed.com to the Allow iframes from this domain list, then updated the web part again.
