Getting a "malformed drive id" error on graphClient.Drives["me"]

[Tom-EllisEVENTS]

Hi,

I'm new to the MSGraph API and trying to find my way around, but the lack of proper and up-to-date samples and documentation makes it really hard.

When trying to get an Exel file from OneDrive, the following code fails:

Console.WriteLine("Finding file in OneDrive...");
var driveItem = await graphClient.Drives["me"].Root.ItemWithPath(oneDriveExcelPath).GetAsync();

Error message is: The provided drive id appears to be malformed, or does not represent a valid drive.

Apparently, the ["me"] part seems to be the problem, but that is what numerous examples suggest to be the correct way... 🤨

What am I doing wrong here?
