arcpy.topographic.PolygonToCenterline() not working in geoprocessing tool for ArcGIS Pro

[OveringUMD]

I got the following error

Traceback (most recent call last):
  File "<string>", line 110, in execute
  File "C:\Program Files\ArcGIS\Pro\Resources\ArcPy\arcpy\topographic.py", line 1886, in PolygonToCenterline

Failed to execute (PolygonToCenterline).  " 

when running arcpy.topographic.PolygonToCenterline() in my code. 

Line 110 is:

arcpy.topographic.PolygonToCenterline(dissolve_doors, door_lines, None)

the whole block of code is:

def execute(self, parameters, messages‌‌
"""The source code of the tool."""
door_layer = parameters[0].valueAsText
door = parameters[1].valueAsText
outFC = parameters[2].valueAsText

# memory delete
arcpy.Delete_management("memory")
#output location
arcpy.AddMessage(outFC)
arcpy.AddMessage(door)

#spatial reference
spatial_reference = arcpy.Describe(door_layer).spatialReference

#multi to single
single_doors = 'memory\\single_doors'
arcpy.management.MultipartToSinglepart(door_layer, single_doors)

#buffer
buffer_doors = 'memory\\buffer_doors'
arcpy.analysis.Buffer(single_doors, buffer_doors, "0.1 Feet","FULL","ROUND","NONE",None,"PLANAR")


floor_list =['xxxx']
for item in floor_list:
#select by attribute
floor_id = "FLOOR_ID = '"+ item + "'"
arcpy.AddMessage(floor_id)
door_selection = arcpy.management.SelectLayerByAttribute(buffer_doors, "NEW_SELECTION", floor_id, None)
#dissolve doors
dissolve_doors = 'memory\\dissolve_doors'
arcpy.management.Dissolve(door_selection, dissolve_doors, None, None, "SINGLE_PART", "DISSOLVE_LINES", "")
#polygon to centerline
door_lines = 'memory\\door_lines2'
arcpy.topographic.PolygonToCenterline(dissolve_doors, door_lines, None)

The weird thing is, it runs fine step by step in the Python window.

Anyone know if something is wrong with code? Thing this might be a bug @esri

Work Around: 

arcpy.topographic.PolygonToCenterline()

For some reason this geoprocessing tool does not like to be written to memory. When using the code below to create a feature class, it worked fine. 

 # create output feature class
        out_name = os.path.basename(outFC3)
        out_path = os.path.dirname(outFC3)
        arcpy.management.CreateFeatureclass(out_path, out_name, "POLYLINE", None, "DISABLED", "DISABLED", spatial_reference)

Odd that it does not like being written to memory, definitely something Esri should fix.
