I'm trying to override the "view" action of a custom object, but unable to do so (and getting some odd error messages in the process.)
When the screen first appears, none of the three radio buttons are checked. If I try to select "no override" then I get the following with no additional clarification:
When I try to override with a lightning component (which is ultimately what I'm trying to achieve) then I get the message:
There were custom validation error(s) encountered while saving the affected record(s). The first validation error encountered was "Large is not a supported form factor.".
Any idea as to what's going on here and how I might fix it?

I encountered this on API v42.0 overriding the New Case action with a Lightning component, and ended up having to remove the
<formFactor>Large</formFactor>section from the .object metadata. See this post for more details: Deployment - Error: You can't use the Large form factor with a Lightning component action override
