I'm working on this Trailhead challenge : Save and Load Records with a Server-Side Controller
As required, I've created an Apex class to write my server-side controller - CampingItemController.
My code seems perfectly alright. I've tried with other code too that seems to work for others too. 
The problem is that my console tells me that Camping_Item__c is an invalid type. I don't seem to understand where I went wrong. Would appreciate if someone couldhelp me with this. Have been stuck with this for a really long time.
