How to use eos-sharp with ASP.NET Core web API?

Question

I am writing web API to get users data from multi-index table data. Below is my API method:

[HttpGet]
        public async IAsyncEnumerable<GetTableRowsResponse>  GetUsers()
            //public async Task<IHttpActionResult> GetUsers()
        {
            Eos eos = new Eos(new EosConfigurator()
            {
                HttpEndpoint = "http://127.0.0.1:8888/v1/chain", //running nodeos on localhost
                ChainId = "nodeoschainid",
                ExpireSeconds = 60,
                SignProvider = new DefaultSignProvider("MyPK")
            });

            var result = await eos.GetTableRows(new GetTableRowsRequest()
            {
                json = true,
                code = "groupacc",
                scope = "groupacc",
                table = "users"
            });

            yield return result;
        }

This is throwing exception:

ApiErrorException: Exception of type 'EosSharp.Core.Exceptions.ApiErrorException' was thrown.

I have users data in multi-index table users and return all users from API. can anybody help me with the error and return types? Also I am not sure about return type IAsyncEnumerable and yield return with async.

I used JsonConvert. The complete code is below:

public async Task<string> GetUsers(string code, string scope, string table)
{
            try
            {
                Eos eos = new Eos(new EosConfigurator()
                {
                   HttpEndpoint = "http://127.0.0.1:8888/v1/chain", 
                   ChainId = "nodeoschainid",
                   ExpireSeconds = 60,
                   SignProvider = new DefaultSignProvider("MyPK")
                });
                GetTableRowsResponse result = await eos.GetTableRows(new GetTableRowsRequest()
                {
                    json = true,
                    code = "groupacc",
                    scope = "groupacc",
                    table = "users"
                });

                string resultJson = JsonConvert.SerializeObject(result.rows);
                return resultJson;

            }
            catch (Exception)
            {
                throw;
            }
  }
