I am trying to create a button that is invoking a VF page which accesses a controller that is a Managed Package object.
The code in VF page is a basic code to display title.
<apex:page standardController="CameleonCPQ__Quote__c"
lightningstylesheets="true" extensions="ContractClone">
<apex:sectionHeader title="Close Quote"/>
</apex:page>
However, when I click on the button - it gives me an error. What could be the possible reason for this?
