Hi i try to create the service to return string

public async Task<string> GetRunningNoDocStrService(string DocTyp, string DocDate, string YearTyp, string DepCode)
        {
            EnsureConnectionOpen();

            SqlParameter[] param = {new SqlParameter("@sndDoctyp", DocTyp),
                                    new SqlParameter("@sndDocDate", DocDate),
                                    new SqlParameter("@sndYearType", YearTyp),
                                    new SqlParameter("@sndDepCode", DepCode)};

            using (var command = CreateCommand("exec.dbo.DocumentNumberSP @sndDoctyp,@sndDocDate,@sndYearType,@sndDepCode", CommandType.Text, param))
            {                
                var DocNo = (await command.ExecuteScalarAsync()).ToString();              
                
                return DocNo;
            }
        
        }

On Angular
this._dbmtabStoreP.getDbmtabStorePUserNames().subscribe((result) => {
            
            console.log("getDbmtabStorePUserNames:",result);         
        });

and this error show
