Your Element.GetGeometry node is outputting a line, however your python script is expecting a point. You will have to break the line down to points with a geometry Points node

I didn’t understand, sorry I’m newbie please explain elaborate.

You are asking Python to give you ONE X and ONE Y value for a line.

As a line is a curve and a curve is the collection of all points between it’s start and end value, there is no ONE X or ONE Y, but an infinite series of values.

So before you can pull the X and Y value, you need to select one point on the curve.

For some of the elements such as window, door, tags you will get a point as an output if you use Element.GetLocation, for some of the elements such as Walls you will get a line as an output. Check the result of your Element.GetLocation and see if you have lines or points. You need to connect points to the python node to make it worked.

Actually, that dynamo working fine for other file, I face that issue got one file only.
