'FamilyInstance' object has no attribute 'Symbol'

I have just encountered this issue, which is pretty weird:

Here’s the code, I have the API loaded:

import sys
import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *

clr.AddReference("RevitAPI")
clr.AddReference("RevitAPIUI")

import Autodesk 
from Autodesk.Revit.DB import *
from Autodesk.Revit.UI import *


x, y, i = 0, 0, 0
xList, yList = [], []
types, ids = [], []


detItemTypes = IN[1]

def getDetItemType(elemName, itemsList):
	if "FHF" in elemName:
		return(itemsList[0])
#	elif ""		


for entrance in IN[0]:

	x += 50000
	y = 0
	i = x
	
	for level in entrance:
	
		x = i	
		y += 1500
		
		for apartment in level[0]:
			x -= 1500
			for elem in apartment:
				xList.append(x)
				yList.append(y)
				x -= 500
				types.append(elem.Symbol)
				ids.append(elem.Id)
				
		x = i
		
		for apartment in level[1]:
			x += 1500
			for elem in apartment:
				xList.append(x)
				yList.append(y)
				x += 500
				types.append(elem.Name)
				ids.append(elem.Id)


OUT = xList, yList, types, ids

This is the line, that throws the exception:

types.append(elem.Symbol)

What could be wrong? This is the standard way of getting the FamilySymbol from a FamilyInstance… Those family instances are all Mechanical Equipment in this case, not that it should matter…

Looks like you’re not unwrapping your elements. Are you feeding Revit objects or Dynamo objects?
