I am getting exception while running the ingest-convert tool that converts elastic search parsing json to logstash configuration.

Exception in thread "main" javax.script.ScriptException: TypeError: Cannot read property "map" from undefined in at line number 78

I would like some help to resolve the issue. It seems like the exception coming at json parser lib used in the tool.

Looking forward to hear. Thanks in advance
