when passing a location to a different class it passed as null

So I have this code that passes locations to a different class but when I try to access the locations from the other class it returns as null. Here is the code that creates the location:

Code:

 World claimworld = plugin.getWorld(plugin.claimsConfig.getString(i + "ClaimWorld"));
              
                Location loc1 = new Location(claimworld, plugin.claimsConfig.getDouble(i + "Claiml1X"), 1, plugin.claimsConfig.getDouble(i + "Claiml1Z"));
                Location loc2 = new Location(claimworld, plugin.claimsConfig.getDouble(i + "Claiml2X"), 256, plugin.claimsConfig.getDouble(i + "Claiml2Z"));
                

and the line i get the error (NPE) on is:

Code:

area.area(loc1, loc2);

which just passes the location to the area class where all I do is location.getblockx and it returns as null.
