Object has no attribute 'get_all' when calling calendar.get_schedule.post()

[hiitsmax]

I'm currently trying to get a room schedule through this code:

credential = ClientSecretCredential(
    config['tenantID'],
    config['clientID'],
    config['clientSecret']
)
scopes = ['https://graph.microsoft.com/.default']
client = GraphServiceClient(credentials=credential, scopes=scopes)

# GET /users/{id | userPrincipalName}
async def get_rooms():
    
    request_body = GetSchedulePostRequestBody(
        schedules = [
            "StanzaA@qq7h.onmicrosoft.com"
        ],
        start_time = DateTimeTimeZone(
            date_time = "2023-03-15T09:00:00",
            time_zone = "Pacific Standard Time",
        ),
        end_time = DateTimeTimeZone(
            date_time = "2023-12-15T18:00:00",
            time_zone = "Pacific Standard Time",
        ),
        availability_view_interval = 60,
    )

    request_configuration = GetScheduleRequestBuilder.GetScheduleRequestBuilderPostRequestConfiguration(
    headers = {
            'Prefer' : "outlook.timezone=\"Pacific Standard Time\"",
    }

    )

    result = await client.me.calendar.get_schedule.post(request_body, request_configuration = request_configuration)


    if result:
        print(result.value)

asyncio.run(get_rooms())

But when running I get an error coming from kiota

same issue here when trying to execute the sample from code from: https://learn.microsoft.com/en-us/graph/api/application-list?view=graph-rest-1.0&tabs=python#example-3-use-filter-and-top-to-get-one-application-with-a-display-name-that-starts-with-a-including-a-count-of-returned-objects

Same issue with this example when I try to modify the header in MessageItemRequestBuilder.MessageItemRequestBuilderGetRequestConfiguration()

https://learn.microsoft.com/es-es/graph/api/message-get?view=graph-rest-1.0&tabs=python#example-3-get-message-body-in-text-format

This was a problem for me as well posting updates to Tasks, example code here.

I investigated and it appears there is a new class that contains the headers now "HeadersCollection", this is used by the base class "BaseRequestConfiguration". So when following documentation examples, it overrides the object with a normal dict, thus the method 'get_all' doesn't exist. Maybe Microsoft is too good for dicts now.

I needed to do the following:
Before:

request_configuration = DetailsRequestBuilder.DetailsRequestBuilderPatchRequestConfiguration(
headers = {
		'Prefer' : "return=representation",
		'If-Match' : "W/\"JzEtVGFzayAgQEBAQEBAQEBAQEBAQEBAWCc=\"",
})

After:

request_configuration = DetailsRequestBuilder.DetailsRequestBuilderPatchRequestConfiguration()
requestConfig.headers.try_add('Prefer','return=representation')
requestConfig.headers.try_add('If-Match','W/\"JzEtVGFzayAgQEBAQEBAQEBAQEBAQEBAWCc=\"')              

Good luck,

Adding some other findings regarding 'HeadersCollection' object/class.

The headers are now very sticky.
Once the headers have been added to the internal dict for the session, they persist between calls. Previously the dict would have wiped out when adding new headers (setting a new dict of headers, wiped old dict of headers). I needed to do this manually or my headers were polluted, resulting in subsequent requests throwing error on invalid ETAGs in my case.

Example from documentation (fixed):

...
request_configuration = DetailsRequestBuilder.DetailsRequestBuilderPatchRequestConfiguration()
requestConfig.headers.try_add('Prefer','return=representation')
requestConfig.headers.try_add('If-Match','W/\"JzEtVGFzayAgQEBAQEBAQEBAQEBAQEBAWCc=\"')    
result = await graph_client.planner.tasks.by_planner_task_id('plannerTask-id').details.patch(request_body, request_configuration = request_configuration)
requestConfig.headers.remove('Prefer') #single session object holding header keys beyond one request, so we clear them
requestConfig.headers.remove('If-Match')

request_configuration = DetailsRequestBuilder.DetailsRequestBuilderPatchRequestConfiguration()
requestConfig.headers.try_add('Prefer','return=representation')
requestConfig.headers.try_add('If-Match','NEXT ETAG')    
result = await graph_client.planner.tasks.by_planner_task_id('plannerTask-id').details.patch(request_body, request_configuration = request_configuration)
requestConfig.headers.remove('Prefer') #single session object holding header keys beyond one request, so we clear them
requestConfig.headers.remove('If-Match')

Seems like a lot of garbage code in my opinion, but editing the dict directly was not working for me.
For example:

request_configuration = DetailsRequestBuilder.DetailsRequestBuilderPatchRequestConfiguration()
request_configuration.headers._headers = {
		'Prefer' : "return=representation",
		'If-Match' : "W/\"JzEtVGFzayAgQEBAQEBAQEBAQEBAQEBAWCc=\"",
}

In my case, changing this code:

post_request_configuration = SubscriptionsRequestBuilder.SubscriptionsRequestBuilderPostRequestConfiguration(
    headers={
        "Prefer": 'IdType="ImmutableId"'
    }
)

to this:

post_request_configuration = SubscriptionsRequestBuilder.SubscriptionsRequestBuilderPostRequestConfiguration()
post_request_configuration.headers.try_add("Prefer", 'IdType="ImmutableId"')

solved the issue.
