IndexError on graph_client.planner.plans.by_planner_plan_id(planId).tasks.get()

[tommeer]

Describe the bug

I get an occasional string index out of range error when calling the function graph_client.planner.plans.by_planner_plan_id(planId).tasks.get().
I ran it against 109 plans and i was able to retrieve 90 succesful. The failed ones retrieved fine when using Graph Explorer.

I'm running the following code:

import asyncio
import configparser
from azure.identity.aio import ClientSecretCredential
from msgraph.graph_service_client import GraphServiceClient

async def main():
    config = configparser.ConfigParser()
    config.read(['config.cfg', 'config.dev.cfg'])

    credentials = ClientSecretCredential(
        config.get('azure','tenantId'),
        config.get('azure','clientId'),
        config.get('azure','clientSecret'),
    )
    scopes = ['https://graph.microsoft.com/.default']

    graph_client = GraphServiceClient(credentials, scopes)
    planId = config.get('app','planId')
    result = await graph_client.planner.plans.by_planner_plan_id(planId).tasks.get()

asyncio.run(main())

Expected behavior

Returned data just like other plans that do seem to work.
Also running the same plan ID in Graph Explorer gives the expected output.

How to reproduce

I ran the the following code and it fails always on the same plan id's.

import asyncio
import configparser
from azure.identity.aio import ClientSecretCredential
from msgraph.graph_service_client import GraphServiceClient

async def main():
    config = configparser.ConfigParser()
    config.read(['config.cfg', 'config.dev.cfg'])

    credentials = ClientSecretCredential(
        config.get('azure','tenantId'),
        config.get('azure','clientId'),
        config.get('azure','clientSecret'),
    )
    scopes = ['https://graph.microsoft.com/.default']

    graph_client = GraphServiceClient(credentials, scopes)
    planId = config.get('app','planId')
    result = await graph_client.planner.plans.by_planner_plan_id(planId).tasks.get()

asyncio.run(main())
