i build an assitant and i comunicate with him with the api.  
i add messages and run thread and get response, after i use tool,i want to submit the tool and i try to submit tool output

The newRun.RequiredAction.SubmitToolOutputs.ToolCalls[0].Id is correct

my code

```
var toolOutputResponse = await PostAsJsonAsync($"v1/threads/{threadId}/runs/{newRun.Id}/submit_tool_outputs",
                                    new ToolsOutput(newRun.RequiredAction.SubmitToolOutputs.ToolCalls[0].Id,"{\"Success\":\"true\"}"));

public class ToolsOutput
    {
        [JsonProperty("tool_call_id")]
        public string ToolCallId { get; set; }
        [JsonProperty("output")]
        public string Output { get; set; }

        public ToolsOutput(string toolCallId, string output)
        {
            ToolCallId = toolCallId;
            Output = output;
        }
    }

```

i found the problem  
i change the code to

```
 ToolsOutput toolsOutput = new ToolsOutput(newRun.RequiredAction.SubmitToolOutputs.ToolCalls[0].Id, "{\"Success\":\"true\"}");

                                // Initialize the SubmitToolOutputs object with an array of one ToolsOutput
                                SubmitToolOutputs submitToolOutputs = new SubmitToolOutputs
                                {
                                    ToolsOutput = new ToolsOutput[] { toolsOutput }
                                };

                                var toolOutputResponse = await PostAsJsonAsync($"v1/threads/{threadId}/runs/{newRun.Id}/submit_tool_outputs",
                                    submitToolOutputs);

public class SubmitToolOutputs
    {
        [JsonProperty("tool_outputs")]
        public ToolsOutput[] ToolsOutput { get; set; }
    }

    public class ToolsOutput
    {
        [JsonProperty("tool_call_id")]
        public string ToolCallId { get; set; }
        [JsonProperty("output")]
        public string Output { get; set; }

        public ToolsOutput(string toolCallId, string output)
        {
            ToolCallId = toolCallId;
            Output = output;
        }
    }

```
