Nullability of reference types in return type of 'List<Tool>? ToolCallHandlerWrapper.OnGetAvailableTools(List<Tool>? registeredTools)' doesn't match implicitly implemented member 'List<Tool> IToolCallHandler.OnGetAvailableTools(List<Tool>? registeredTools)' (possibly because of nullability attributes).

Argument of type 'List<IMessage?>' cannot be used for parameter 'Messages' of type 'List<IMessage>' in 'ChatGPTRequest.ChatGPTRequest(List<IMessage> Messages, string Model, double? FrequencyPenalty = null, Dictionary<int, int>? LogitBias = null, bool? Logprobs = null, int? TopLogprobs = null, long? MaxTokens = null, long? N = null, double? PresencePenalty = null, string[]? Stop = null, bool? Stream = null, StreamOptions? StreamOptions = null, double? Temperature = null, double? TopP = null, List<Tool>? Tools = null, ToolChoice? ToolChoice = null, bool? ParallelToolCalls = null, string? User = null)' due to differences in the nullability of reference types.

Possible null reference return.

This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread.
