How to create event in a calendar?

[gugupy]

What I am missing here?

import asyncio
import datetime

from azure.identity.aio import ClientSecretCredential
from msgraph import GraphServiceClient

TENANT_ID = ''
CLIENT_ID = ''
CLIENT_SECRET = ''
SCOPES = ['https://graph.microsoft.com/.default', 'Calendar.ReadWrite']


async def get_graph_client():
    credential = ClientSecretCredential(
        client_id=CLIENT_ID,
        tenant_id=TENANT_ID,
        client_secret=CLIENT_SECRET,
    )
    return GraphServiceClient(credential, scopes=SCOPES)


async def create_outlook_event(
    subject, content, start_time, end_time, time_zone, user_id
):
    graph_client = await get_graph_client()

    event = {
        'subject': subject,
        'body': {'contentType': 'HTML', 'content': content},
        'start': {'dateTime': start_time.isoformat(), 'timeZone': time_zone},
        'end': {'dateTime': end_time.isoformat(), 'timeZone': time_zone},
        'location': {'displayName': 'Online'},
    }

    created_event = await graph_client.users.by_user_id(
        user_id
    ).calendar.events.post(event)
    return created_event


async def main():
    subject = 'Appointment Booking'
    content = 'This is a test appointment booked via the Graph API.'
    start_time = datetime.datetime(
        2025, 4, 1, 10, 0, 0
    )  # year, month, day, hour, minute, second.
    end_time = datetime.datetime(2025, 4, 1, 11, 0, 0)
    time_zone = 'Asia/Kolkata' 
    try:
        created_event = await create_outlook_event(
            subject,
            content,
            start_time,
            end_time,
            time_zone,
            'email',
        )
        print('Event created:', created_event.subject)
    except Exception as e:
        raise Exception('Error creating event: {}'.format(e)) from e



if __name__ == '__main__':
    asyncio.run(main())

I am getting -- Exception: Error creating event: 'dict' object has no attribute 'serialize'

Any help would be appreciated.

I had some problem with my sdk installation. After the reinstalling the sdk I am able to using msgraph.generated module, which helped to fix above.
