Microsoft Graph .NET SDK returns Invalid Request (400) when trying to CreateLink

Question

Hello,

I'm using latest version of Microsoft Graph .NET SDK (5.11.0). What I'm trying to accomplish is to Create shareable link for an item that's stored in SharePoint site drive. I've been trying to follow the Graph API documentation here

public async Task<Result<string>> CreateShare(string requestUri)
{
    var client = GetOrCreateSharepointClient();
   
    var requestBody = new Microsoft.Graph.Drives.Item.Items.Item.CreateLink.CreateLinkPostRequestBody
    {
        Type = "edit",
        Scope = "anonymous"
    };

 	var item = client.Drives[myDriveId].Items["root:/" + pathToFile];
    var permission = await item.CreateLink.PostAsync(requestBody);

    return Result.Success<string>(/* return link here */);
}

However the line item.CreateLink.PostAsync(requestBody) throws an ODataError exception with the error message Invalid Request, status code 400. I've tried to use different properties and values in the requestBody as well.

There shouldn't be any problem with permissions, I've enabled that files can be shared with anyone and the application has permissions to Files.ReadWrite.All, Sites.ReadWrite.All

Appreciate any help in advance.

[Microsoft Graph .NET SDK returns Invalid Request (400) when trying to CreateLink]

Issue Symptom:

Create shareable link return 400 Invalid Request.

Solution:

Fixed the issue with following code

var item = client.Drives[myDriveId].Items["root"].ItemWithPath(pathToFile);

When using .GetAsync() .DeleteAsync(), the former syntax worked without an issue.

Answer 2

I've managed to fix this issue. The problem is with this line

var item = client.Drives[myDriveId].Items["root:/" + pathToFile];

Should look like this:

var item = client.Drives[myDriveId].Items["root"].ItemWithPath(pathToFile);

When I was using .GetAsync() .DeleteAsync(), the former syntax worked for me without an issue.
