Hi, Iam using Nifi 1.3 version and this is the flow..getsftp->putsftp->putsftp. But at times after the files are picked by getsftp,say if its 190 bytes then putsftp transfers as 0 bytes. It doesnot happen all the time but at times. Please find below the error: 2019-01-07 02:00:01,272 ERROR [Timer-Driven Process Thread-7] o.a.nifi.processors.standard.PutSFTP PutSFTP[id=XXX] PutSFTP[id=XXX] failed to process session due to org.apache.nifi.processor.exception.MissingFlowFileException: Unable to find content for FlowFile: {}
