I am trying to configure my Lightning component to show up on the Lightning app builder, and tried to implement the interface as listed in docs,
<aura:component controller="stech.CalendarController" implements="flexipage:availableForAllPageTypes">
But I am getting an error Failed to save undefined: No INTERFACE named markup://flexipage:availableForAllPageTypes found : [markup://stech:calendar]: Source
I tried adding namespaces but I get a different error then Failed to save undefined: Invalid Descriptor Format: flexipage:stech.availableForAllPageTypes[INTERFACE]: Source
Does anyone know how to use this interface? Also related question, how do I add design resource to the bundle?
PS:I have the Lightning App Builder enabled in the org
