Catch 22

I have a SharePoint list that passed the dreaded 5000 limit.
Trying to add an indexed to the list results in:

Sorry, something went wrong

The attempted operation is prohibited because it exceeds the list view threshold enforced by the administrator.

In order to overcome the dreaded 5000 limit in SharePoint you need to create a view on an index item. But you cannot create an index on a list with more than 5000 items.

Hey SharePoint Expert,

Please make a comment tell me what I missed.🤢
