Help: Error from executing BRApi.Utilities.ExecRemoteGatewayBusinessRule

[liyinan357]

Hello,

First time posting question here. I'm a developer new to the OneStream.

I'm trying to run a remote business rule to pull a file that stored on Local Gateway Server. The idea is to have the content of the data file returned to OS in bytes[]. 

I have extender rule  and SIC Function rule. After I executed the Extender rule, I printed out a few things from the returned object and looks like there is an exception when executing the remote rule. Could anyone give any pointers? Any help is appreciated!

 Error Returned

BRApi.ErrorLog.LogMessage(si,objRemoteRequestResultDto.RemoteException.StackTrace)
' Returned -> 
'    at OneStream.Shared.Wcf.RelayHostInfo.InvokeRequest(IRemoteRequestBase xfRequest)
'    at OneStream.Shared.Wcf.OneStreamRelayAgent.SendRelayRequest(IRemoteRequestBase xfRequest)
BRApi.ErrorLog.LogMessage(si,objRemoteRequestResultDto.RemoteException.GetBaseException.Message)
' Returned -> 
'    DirectConnection
BRApi.ErrorLog.LogMessage(si,objRemoteRequestResultDto.RemoteResultStatus)
' Returned -> 
'    64 (which indicates an exception)

Here is my extender rule

Change/add the very first line of code to this:
What does it show in the log?:

BRApi.ErrorLog.LogMessage(si,objRemoteRequestResultDto.RemoteException.Message)

Thanks for your response!

I added the line of code and it printed out "DirectConnection"
