Jigasi Install and run ( TranscriptionGateway is disabled)

I have downloaded the jigasi source code and built it as mentioned
Basically I want to show the transcription.Wherever TranscriptionGateway gets null

This error ocures When I run the jigasi.sh file from target/jigasi…/

In that case how can this problem be solved,Can anyone give me the right solution?
