Hi @Garrett 

Can you please share your SharePoint Column settings and type for this field?

Hi @Prineel_V3, 

Thanks for responding.

The column is People Type.

Name of Supported-By (Email) - Not recognized
Name of Supported-By (display Name) - Not recognized
Name of Supported-By (ID) - Is recognized

Its the same result when I use the SPO - Retrieve an Item and SPO - Query List actions. 
I need to send an email to the “Name of Supported-By” user but cannot retrieve the values

Hi @Garrett ,

If you are only using people and not groups,  please change “allow selection” to people only (if you are using groups, then it gets complicated). You can then re-connect to your connection and re-configure your start event or re-upgrade your workflow if you haven't made any changes.

Hope this helps :)

Hey @Prineel_V3 

Yes, that most definitely helps. 

Thanks so much
