   @tiwarinaman  Looks like the cause is that formatFunction is not set automatically in writeCustomType. Does it raise the same error if not setting skipIfEmpty?
   
   TextIO.write also supports skipIfEmpty and it sets formatFunction in its to() method. For writeCustomType you may need to manually set formatFunction. 
   
   Indeed, documentation needs to be improved.
