Graph explorer C# snippets do not work with Microsoft.Graph" Version="5.9.0"

To get just selected fields, I test in Graph explorer

https://graph.microsoft.com/v1.0/sites/372ddaf5-60a1-46d4-bb19-2f80c9ba32b3/lists/DPC-Job-Master/items?expand=fields(select=Title,RequestForLookupId,Completion,CurrentQueue,DoneReceived)&$filter=fields/Completion gt '2023-05-04T09:15:32.6473018Z' and fields/CurrentQueue eq 'Done' and fields/DoneReceived eq null

it works fine. the snippet is:

var result = await graphClient.Sites["{site-id}"].Lists["{list-id}"].Items.GetAsync((requestConfiguration) =>
{
	requestConfiguration.QueryParameters.Expand = new string []{ "fields(select=Title,RequestForLookupId,Completion,CurrentQueue,DoneReceived)" };
	requestConfiguration.QueryParameters.Filter = "fields/Completion gt '2023-05-04T09:15:32.6473018Z' and fields/CurrentQueue eq 'Done' and fields/DoneReceived eq null";
});

When using the snippet in my code it failes with:

"Parsing OData Select and Expand failed: Term '(select=Title,RequestForLookupId,Completion,CurrentQueue,DoneReceived)' is not valid in a $select or $expand expression."

Is there a better way to figure out the syntax that will work?
Thank you

If you try to get request information and check what url is generated by 5.9.0

var request = graphClient.Sites["{site-id}"].Lists["{list-id}"].Items.ToGetRequestInformation((requestConfiguration) =>
            {
                requestConfiguration.QueryParameters.Expand = new string[] { "fields(select=Title,RequestForLookupId,Completion,CurrentQueue,DoneReceived)" };
                requestConfiguration.QueryParameters.Filter = "fields/Completion gt '2023-05-04T09:15:32.6473018Z' and fields/CurrentQueue eq 'Done' and fields/DoneReceived eq null";
            });

result.URI.AbsoluteUri has the value

https://graph.microsoft.com/v1.0/sites/%7Bsite-id%7D/lists/%7Blist-id%7D/items?%24filter=fields%2FCompletion%20gt%20%272023-05-04T09%3A15%3A32.6473018Z%27%20and%20fields%2FCurrentQueue%20eq%20%27Done%27%20and%20fields%2FDoneReceived%20eq%20null&%24expand=fields%28select%3DTitle%2CRequestForLookupId%2CCompletion%2CCurrentQueue%2CDoneReceived%29

Decoded

https://graph.microsoft.com/v1.0/sites/{site-id}/lists/{list-id}/items?$filter=fields/Completion gt '2023-05-04T09:15:32.6473018Z' and fields/CurrentQueue eq 'Done' and fields/DoneReceived eq null&$expand=fields(select=Title,RequestForLookupId,Completion,CurrentQueue,DoneReceived)

You can see that SDK generates $expand instead of expand.

As a quick fix you can use $select inside Expand:

var result = await graphClient.Sites["{site-id}"].Lists["{list-id}"].Items.GetAsync((requestConfiguration) =>
{
    // $select instead of select
    requestConfiguration.QueryParameters.Expand = new string []{ "fields($select=Title,RequestForLookupId,Completion,CurrentQueue,DoneReceived)" };
    requestConfiguration.QueryParameters.Filter = "fields/Completion gt '2023-05-04T09:15:32.6473018Z' and fields/CurrentQueue eq 'Done' and fields/DoneReceived eq null";
});
