This error occur when I copied this spell along with its libraries http://www.hiveworkshop.com/forums/...-1-a-153621/?prev=search=disciple&d=list&r=20

As far as I am aware the LUA functionality required for "external object merger" has not been functional for a long time (since JNGP stopped officially being maintained at WC3C). I believe some unofficial JassHelper revisions released since do fix the functionality but I am unsure.

Well the spell goes ok, so I guess i can just let it error like that right?

Any sort of error is generally bad, especially with JassHelper. It can prevent the map script from being built or cause systems that involve the error to not work correctly.
