Forecast Plugin - Error in R process: simple Error : parse error: premature EOF

[Caio0109]

I try to run my plugin but I still receiving this message: 

Job failed: Error in R process: simpleError : parse error: premature EOF (right here) ------^

The log: 

com.dataiku.common.server.APIError$SerializedErrorException: Error in R process: simpleError :  parse error: premature EOF

Hi @Caio0109,

It seems like you may be using the legacy forecast plugin, is that correct? Please note that indeed this plugin is deprecated, and you'll want to move on to the built-in timeseries forecasting features, which will be more robust, instead: https://doc.dataiku.com/dss/latest/machine-learning/time-series-forecasting/index.html

Let us know if you have trouble using the native feature(s)! 

Thank you,
