I need Recommendations to fetch the Recommendations record but when i used GetRecommendationsAsync as inside that pass request i get error like {"message":"Index does not exist","status":404} i double check everything like index name and api key and permissions as well. So any solution.

var requests = new List {
new RecommendRequest {
IndexName = l.Items[0].Name, //here is index name
ObjectID = "333434349435",
Model = "related-products",
Threshold = 10,
MaxRecommendations = 10,
QueryParameters = new Query(),
FallbackParameters = new Query()
}
};

        var recommendationClient = new RecommendClient(algApplicationId, algAdminApiKey);

        var res = client.GetApiKey(algAdminApiKey);

        if (res.Acl.Contains("recommendation"))
        {
            Console.WriteLine("ok");
        }

        try
        {
            
            var task = Task.Run(() => recommendationClient.GetRecommendationsAsync<NewsDetail>(requests));
            if (task.Wait(TimeSpan.FromSeconds(300)))
            {
                var response = task;
                Console.WriteLine($"ObjectID: {response}");
            }
            else
            {
                throw new Exception("Request Timed out");
            }
        }
        catch (AggregateException ex)
        {

            foreach (var inner in ex.InnerExceptions)
            {
                Console.WriteLine(inner.Message);
            }

        }
