How do i get GUID from type of 'PlaneSurface' in GH_Python

I have two 'PlaneSurface' input Parameter in GH_pyhton.And i want to use `booleanUnion` these input . But it got error below.

*x,y=PlaneSurface

code

import rhinoscriptsyntax as rs
print(type( x ))
arr=[]
arr.append( x )
arr.append( y )
#print(arr)
rs.BooleanUnion( arr )
a=arr

error

Runtime error (ValueErrorException): unable to convert <Rhino.Geometry.PlaneSurface object at 0x000000000000003A [Rhino.Geometry.PlaneSurface]> into Brep geometry

maybe i have to use type of GUID inputParameter of 'booleanUnion'.How can i get GUID from type of PlaneSurface?

You could either set the "Type Hint" on the Python component to "Dynamic (rhinoscript GUID when geometry)" for the input surfaces, or, use a corresponding RhinoCommon functionality directly. I think that someone did post about getting GUIDs from objects, but it is really a sort of roundabout way of going about it I find. Also make sure you assign the boolean function to a variable like so:

a = rs.BooleanUnion(arr)

I setted GUIDs to "BooleanUnion" 's argument. But "BooleanUnion" did not expect Guid.

What should i set to "BooleanUnion" 's argument?

Have a look at the attached files, they seem to work without throwing any errors. That said, I'm not exactly sure that the boolean union results are what you are looking for.
