Error occurred in deployment step 'Activate Features': Object reference not set to an instance of an object. This is a common Error that every SharePoint developer will do.

We cannot use SPContext.Current.Web in feature receivers. They can be run by the timer service or powershell which does not have access to the SPContext.

using (SPSite site = (SPSite)properties.Feature.Parent)

{

   using (SPWeb web = site.OpenWeb())
