Error when doing query for drives on Sharepoint using Microsoft Graph in C#

I have this line of code

Running on an app registration with these permissions

In a basic .NET Core 7 app with added Microsoft.Graph client configured like this

Sometimes this finds a drive for a given folderName successfully and other times, for the exact same folder name, it throws a general exception.

It returns exception:

General exception while processing at 

• Microsoft.Kiota.Http.HttpClientLibrary.HttpClientRequestAdapter.ThrowIfFailedResponse(HttpResponseMessage response, Dictionary`2 errorMapping, Activity activityForAttributes, CancellationToken cancellationToken) at Microsoft.Kiota.Http.HttpClientLibrary.HttpClientRequestAdapter.SendAsync[ModelType](RequestInformation requestInfo, ParsableFactory`1 factory, Dictionary`2 errorMapping, CancellationToken cancellationToken)

     at Microsoft.Graph.Drives.Item.SearchWithQ.SearchWithQRequestBuilder.GetAsSearchWithQGetResponseAsync(Action`1 requestConfiguration, CancellationToken cancellationToken)

What am I missing?

Thanks in advance!
