AzureCognitiveSearchChatExtensionConfiguration help

Question

Hi guys

I'm trying to setup AzureCognitiveSearchChatExtensionConfiguration for hybrid search (vector + semantic) but I can't make it work

Here is my code

        var search=new AzureCognitiveSearchChatExtensionConfiguration()
        {
            SearchEndpoint = new Uri(_configuration.GetSection("AppSettings")["SearchEndPoint"]),
            IndexName = "ai"
           
        };
        search.SetSearchKey(_configuration.GetSection("AppSettings")["SearchKey"]);
        search.SemanticConfiguration="ai-semantic-config";
        search.QueryType= AzureCognitiveSearchQueryType.VectorSemanticHybrid;
        search.EmbeddingEndpoint =new Uri(_configuration.GetSection("AppSettings")["AiEndPoint"]);///openai/deployments/{deployment-id}/embeddings?api-version={api-version}
        search.SetEmbeddingKey(_configuration.GetSection("AppSettings")["AiKey"]);
        search.FieldMappingOptions = new AzureCognitiveSearchIndexFieldMappingOptions()
        {
            UrlFieldName="Url",
            TitleFieldName="Title",
        }
    ;
        search.FieldMappingOptions.ContentFieldNames.Add("Content");
        search.FieldMappingOptions.ContentFieldNames.Add("Subtitle");
        search.FieldMappingOptions.ContentFieldNames.Add("Authors");
        //search.FieldMappingOptions.VectorFieldNames.Add("TitleVector");
        search.FieldMappingOptions.VectorFieldNames.Add("ContentVector");
       

        ChatCompletionsOptions chatCompletionsOptions = new()
        {
            DeploymentName = modelName,
            Messages =
{
    new ChatMessage(
        ChatRole.System,
        "You are a helpful assistant "),
    new ChatMessage(ChatRole.User, question)
},

            AzureExtensionsOptions = new AzureChatExtensionsOptions()
            {
                Extensions =
    {
        search
    }
            }
        };






        try
        {
            Response<ChatCompletions> response = await _client.GetChatCompletionsAsync(chatCompletionsOptions);
            ChatMessage message = response.Value.Choices[0].Message;
            return message.Content;

        }

The message I'm getting is

Service request failed. Status: 400 (Bad Request) Content: {"error": {"requestid": "90ef3895-27ce-458f-a6d2-ba0fe165345f", "code": 400, "message": "An error occurred when calling Azure Cognitive Search: Azure Search: Please assign a proper column/field for vector search.

Although I have passed the correct vector filed

Thanks
