non-generic Watch for CRD's without Type

[mmercan]

Describe the bug

I have several CRDs which I don't have types. I have a simple function it lists them as JToken then, rest of the application validate the configuration over JsonPath base rule engine.

`

public async Task<List<JToken>> ListClusterCustomObject(string Group, string Version, string Plural)
{
    var result = await _client.CustomObjects.ListClusterCustomObjectWithHttpMessagesAsync(Group, Version, Plural);

    var jToken = JToken.Parse(result.Body.ToString());
    var res = jToken?.SelectToken("items")?.ToList();
    if (res == null)
    {
        res = new List<JToken>();
    }
    return res;
}

`

A clear and concise description of what the bug is.

I am trying to create a similar function over Watch I have tried several methods and I have failed.
is there any method I can use for Watch which can return Response Body then I can convert it to JToken ?
or do you have any suggestion on how to work with Watch without having POCO classes for the CRD types.

JToken is a Newtonsoft.Json object, this library uses System.Text.Json, you can try using JsonDocument and JsonElement.

Alternatively, you can generate types for the CRDs using https://github.com/IvanJosipovic/KubernetesCRDModelGen

If I could receive the result.Body (string) over the Watch I could convert it to JToken inside of the my method
JsonDocument and JsonElement still doesn't support JsonPath (dotnet/runtime#31068)
is there any way of working with Watch without Deserialization ?

.ListClusterCustomObjectWithHttpMessagesAsync<dynamic>?

Thanks for everyone's help and suggestions, even if I have to take JsonElement and convert to JToken
this method solved my issues.

    Action<WatchEventType, object> onEvent = (a, b) =>
    {
        if (b is JsonElement content)
        {
            JToken token = JToken.Parse(content.ToString());
            Console.WriteLine(token.ToString());
        }
    };
    Action<Exception>? onError = null;
    Action? onClose = null;


    var result = await client.CustomObjects.ListClusterCustomObjectWithHttpMessagesAsync(Group, Version, Plural, watch: true);
    await Task.FromResult(
                 result.Watch(onEvent, onError, onClose)
     );
