Cannot show the route detail

[JeffYang0706]

Hi all,
After importing the GTFS data (tried different data), when I click a specific route, it doesn't extend the "blue box" to show the route detail info. And the route doesn't appear on the map, either.

Got the error below:
File "F:\gtfs\transitfeed-master\transitfeed\trip.py", line 767, in SortListOfTripByTime
trips.sort(key=GetStartTime)
NameError: global name 'GetStartTime' is not defined

Could someone kindly help me how to solve this problem? Many thanks.
