SetValue of a Text Animator Scale via ExtendScript?

Hello, I'm fresh new in ExtendScript... and I'm trying to solve one question for days...

Can anybody help me to set value of "Scale" inside a
> Text layer > Text > Animator 1 > Scale??

I'm trying this  but is not working...
app.project.item(1).layer(2).property("Text").text.animator("Animator 1").property("Scale").setValue([150,150])
