How to link a mask path to only the x or y position of another layer?
I’m trying to create a wipe text reveal animation where a line moves to horizontally or vertically and reveals text.
I have a mask on the text layer to create this, and I want to link the mask path to just the X parameter of the line layer’s position property (so the mask will move with the line).
When I drag the pick whip on the mask path to the X position of the line layer, I’m given the error
object of type found where a property is needed
Why is this? What can I do to resolve this error? AE newbie here so your help will be appreciated!

Rather than trying to link a mask to a shape, you can use a Track Matte so that the shape itself reveals the text.
On the text layer, select the shape layer with the Track Matte selector. This will show the text layer wherever it intersects with the shape layer. It will also hide (eyeball off) the shape layer, so you’ll have to re-enable it to see both layers in your comp at the same time.
