the following code fails with “InvalidAuthenticationToken”

I am a newbie to Python and learning the best I can but I’m also new to using the GraphSDK (much more familiar with the Okta SDK – I am looking to just basically auth to Entra using an app registration which is working but it fails to do the user lookup and Im not sure why. The error I get is 2024-05-10 09:47:13,899 – ERROR – Error finding user: ‘GraphServiceClient’ object has no attribute ‘get’ but I am not sure what the best way to find the USERID then if there is no get method

Currently creating a small cloud function that will pull messages in an inbox using the microsftgraph sdk for python. I am trying to make it so the app will pull as many messages as possible in the first request, and the way to do this seems to be by adding a ‘top’ query parameter and setting it to 1000 – the max. However the examples provided to achieve this seem to use a function which does not exist? Anyone have any solutions?
