I have seen a strange behavior on SharePoint Online when I tried to create a custom view for Promoted List.
Even if you select Standard or Datasheet view it doesn’t matter.
You must select fields:
- Background Image Location
- Link Location
- Background Image Cluster Horizontal Start
- Background Image Cluster Vertical Start
To be able to have your view working, otherwise you will have the error: “TypeError: Cannot read property ‘indexOf’ of undefined”.
Which is quiet logic if you keep in mind that SharePoint needs those properties to display tiles.
This is good to know that Title field is not mandatory, especially if you want to make a “links-launcher” with your tiles.
To create a view in Promoted Links the best way is to start from the existing view: “All Promoted Links”, then you can select all wanted fields to display.
