The SDK return a List of String when it should return a List of Label [BUG]:

[Hossain2024]

What happened?

I am encountering an issue while trying to retrieve Label objects for an issue on GitHub.

https://github.dev/octokit/dotnet-sdk/blob/main/src/GitHub/Repos/Item/Item/Issues/IssuesRequestBuilder.cs

The GitHub.Models.Issue class defines the label property as a List. Based on the API response it should be a List<Label>

Here is the API call I used:

https://api.github.com/repos/microsoft/kiota/issues/5037

response from the API call (taken from postman)

I want to get the Labels field of this issue which is a List<Label>.

"labels": [
        {
            "id": 2603543073,
            "node_id": "MDU6TGFiZWwyNjAzNTQzMDcz",
            "url": "https://api.github.com/repos/microsoft/kiota/labels/type:bug",
            "name": "type:bug",
            "color": "d73a4a",
            "default": false,
            "description": "A broken experience"
        },
        {
            "id": 3016728568,
            "node_id": "MDU6TGFiZWwzMDE2NzI4NTY4",
            "url": "https://api.github.com/repos/microsoft/kiota/labels/Python",
            "name": "Python",
            "color": "0BBE2D",
            "default": false,
            "description": ""
        }
   ]

Here I am trying to get the Labels field of an issue. The type of the label field is a List<String> but I expect the labels field to be a List where each label object is structured as follows:

  {
            "id": 2603543073,
            "node_id": "MDU6TGFiZWwyNjAzNTQzMDcz",
            "url": "https://api.github.com/repos/microsoft/kiota/labels/type:bug",
            "name": "type:bug",
            "color": "d73a4a",
            "default": false,
            "description": "A broken experience"
  },

on line 3 I get the following error message

 Cannot implicitly convert type 'System.Collections.Generic.List<string>' to 'System.Collections.Generic.List<Label>'[CS0029](https://msdn.microsoft.com/query/roslyn.query?appId%3Droslyn%26k%3Dk%28CS0029%29)
Converting null literal or possible null value to non-nullable type.[CS8600](https://msdn.microsoft.com/query/roslyn.query?appId%3Droslyn%26k%3Dk%28CS8600%29)
List<string>? GitHub.Models.Issue.Labels { get; set; }
'Labels' may be null here.

I am currently receiving a List where the size is 2(for example) and both string [0] and string [1] are null even when [0] has a value and [1] has a value. This is contrary to the actual values in the response. Why is the labels field from the API returning a List instead of a List? what is the datatype of labels field in an issue object.

Hi @Hossain2024, you're simply confusing two endpoints. The GetAllIssuesAsync endpoint (returning multiple issues from the GitHub API) returns a list of label strings. The request to return a single issue returns a more fleshed-out labels object.

If you want to get a single issue that contains all the information about its labels, you can make a request like this:

            var labels = await gitHubClient.Repos["microsoft"]["kiota"].Issues[5037].Labels.GetAsync();
            foreach (var label in labels)
            {
                Console.WriteLine("Label: " + label.Name);
                Console.WriteLine("Label ID: " + label.Id);
                Console.WriteLine("Label Description: " + label.Description);
                Console.WriteLine("Label Color: " + label.Color);
            }

which, if you've initialized your client correctly, will print something like the following:

Label: type:bug
Label ID: 2603543073
Label Description: A broken experience
Label Color: d73a4a
Label: Python
Label ID: 3016728568
Label Description:
Label Color: 0BBE2D
Label: WIP
Label ID: 3162613472
Label Description:
Label Color: F683F1

I hope that helps!
