• Package Name: azure-maps-route
• Package Version: 1.0.0b1
• Operating System: MacOS 14.5
• Python Version: 3.11

Describe the bug When running the code the error message mentioned above in the title appears. The Code:

import os
from azure.core.credentials import AzureKeyCredential
from azure.maps.route import MapsRouteClient

origins = [[11.4544701, 48.7779473]]
destinations = [[11.9667977, 48.9821216]]

def distance_matrix(origins, destinations):
    credential = AzureKeyCredential(os.environ.get("AZURE_SUBSCRIPTION_KEY"))

    route_client = MapsRouteClient(
        credential=credential,
    )

    request_obj = {
        "origins": {
            "type": "MultiPoint",
            "coordinates": origins
        },
        "destinations": {
            "type": "MultiPoint",
            "coordinates": destinations
        }
    }

    result = route_client.get_route_matrix(query=request_obj, use_traffic_data=False, travel_mode="truck", route_type="fastest")
    matrix = []
    for i in result.matrix:
        row = []
        for j in i:
            entry = j.as_dict()
            row.append({
                "length_in_meters": entry["response"]["summary"]["length_in_meters"],
                "travel_time_in_seconds": entry["response"]["summary"]["travel_time_in_seconds"],
            })
        matrix.append(row)
    return matrix

matrix = distance_matrix(origins, destinations)
print(matrix)

Run the code above and the following error occurs:

Process finished with exit code 1

If you replace the coordinates with another coordinate the code works. We've debugged the code and instead of a dict we receive the following string:

Cell could not be processed
