AttributeError: 'NoneType' object has no attribute 'is_junction'

CARLA version:0.9.14
Platform/OS:ubuntu
Problem you have experienced:AttributeError: 'NoneType' object has no attribute 'is_junction'
What you expected to happen: How to resolve it
Steps to reproduce:

1. Open Town01
2. Set ego_start_location = 299.2,330.6,0.561943 （x,y,z）
3. Set end_location = 300.70875,330.906875,0.561943 （x,y,z）
4. agent = BehaviorAgent(vehicle=ego_vehicle, behavior="normal"), ego_vehicle's position is ego_start_location
5. agent.set_destination(end_location=carla.Location(x=end_x, y=end_y, z=end_z)), set destination as end_location
6. with CarlaSyncMode(world, camera_rgb, fps=5) as sync_mode:
   while True:
   control = agent.run_step(debug=False)
   ego_vehicle.apply_control(control)
   if agent.done():
   logger.info(
   "The destination has been reached. Stop the simulation!"
   )
   break

Other information (documentation you consulted, workarounds you tried):

I think the reason for this error is that the waypoint planned in the previous step is already near the key point, so an error will be reported when trying to find the next waypoint, but agent.done() does not become True after the previous step is run, resulting in an error.
