getOLAPFrame has never returned a result even though MDX works

[MrRaymondLee]

I have different error messages when I run MDX. The MDX I tested against the cube and returns values. Right now I'm getting this error in R:

Failed to connect with OLAPRGateway. Error messageargument is of length zeroif (server_resp != "[]") {
    eval(parse(text = server_resp))
}

In the OLAPRGateway.exe console I get this error:

System.ArgumentNullException: String reference not set to an instance of a String.
Parameter name: s
   at System.Text.Encoding.GetBytes(String s)
   at OLAPRGateway.Program.Main(String[] args)
>> flushing and restarting
>> Waiting for client connection on port 8888

Sometimes the query does work in the sense I see data coming in through console but in R I'll get this error:

Failed to connect with OLAPRGateway. Error message<text>:1:185: unexpected ','
1: Date_Day-Month-Quarter-Year_All <- c("0.0280517097695254");Date_Day-Month-Quarter-Year_All_Calendar2010 <- c("0.0290963998535984");Date_Day-Month-Quarter-Year_All_Calendar2010_Quarter1,
                                                                                                                                                                                            ^parse(text = server_resp)

I get the Parameter name: s error after trying various MDX. It's strange that eventually it will "work" again in the sense I get the unexpected , error above.
