Problem with execution of python code on a self-built Carla-UE4-Map

[kuebel329]

Hello, I built Carla from source on Windows and created my own map with a parking garage and a car. Now, I want to execute python code on this map and pressed "Play", which functioned. Then, I went to the commandline , to the folder with the other python scripts and tried to execute my own code with "python test.py". In the python file test.py, there was the following code:

import sys

Add the path to the CARLA .egg file

sys.path.append(r'C:\carla\PythonAPI\carla\dist\carla-0.9.15-py3.7-win-amd64.egg') # Update 'py3.7' if using Python 3.8
import carla
try:
# Connect to the CARLA server
client = carla.Client('localhost', 2000)
client.set_timeout(10.0) # Set a timeout for the connection
print("Successfully connected to CARLA server.")
# Get the current world and print map name to confirm connection
world = client.get_world()
print("Connected to CARLA world:", world.get_map().name)
# List available vehicle blueprints as a test
blueprint_library = world.get_blueprint_library()
vehicle_blueprints = blueprint_library.filter("vehicle.*")
print("Number of available vehicle blueprints:", len(vehicle_blueprints))
except Exception as e:
print("An error occurred:", e)

There comes "Successfully connected to CARLA server.", but unfortuanteley then came the error message: "ERROR: unable to parse the OpenDRIVE XML string An error occurred: failed to generate map". When I try this with Town01, it functions well without a error.
I tried very much and also asked ChatGPT, here it was for example said that I should export xord files and something like that and that this would be very complex. I also know ChatGPT is unreliable, so I don't want to spend much time for a false way.

Does somebody know how I can solve this problem on a preferably easy way? If the only way is exporting xord files, I will do this but I don't want to trust ChatGPT in this case. Thank you for your answers and your help!
