trying to override masterpage items

using CC.

Here's my scripts

tell application "Adobe InDesign CC"

    tell every item of page 1 of document 1

        set allow overrides to true

    end tell

end tell

I get error -10006

Can't set allow overrides of every item of page 1 of document 1 to true

Tried

tell application "Adobe InDesign CC"

    override every item of page 1 of document 1

end tell

got error -1708

every item of page 1 of document 1 doesn't understand the override message

Tried

tell application "Adobe InDesign CC"

    set mypageitems to all page items

    override mypageitems

end tell

Gives me error -1728

Can't get all page items

tell application "Adobe InDesign CC"

    tell masterspread of document 1

        set mypageitems to master page items

        override mypageitems

    end tell

end tell

got error -1728

Can't get master page items of masterspread of document 1

I found this script for katmac75 provided by Shane Stanley from CS5 and it worked (I changed it to CC) but gives an error after completing

error -1708

every item of master page items of page 9 of document 1 whose allow overrides of it = true doesn't understand the override message

-- I switched to a 9 page document to test with.

tell application "Adobe InDesign CC"

    tell document 1

        repeat with i from 1 to count of pages

            override (every item of master page items of page i whose allow overrides is true) destination page page i

        end repeat

    end tell

end tell
