If statement error when using spatial object

[Neico]

I'm trying to create a new variable that contains the spatial information of the variable "SpatialObj" contains null values if the second variable "LEZ_type" is empty (see attachment).

I tried:

IF IsEmpty([LEZ_type]) THEN "" ELSE [SpatialObj] ENDIF

but received an error: "type mismatch on true/false branch of if statement"

Can you please help?

Instead of "" can you try with Null() and also make sure you selected the Data Type as SpatialObj
