Hello,   I am trying Apache Nifi for testing purpose. I create a flow that need to unzip a file that contains an .xml file. I chain those processors: ListFIle => IdentifyMimeType => UnpackContent.   All files I have test are failled. And I have a java error on my logs:   2021-04-09 17:56:40,839 ERROR [Timer-Driven Process Thread-7] o.a.n.processors.standard.UnpackContent UnpackContent[id=b746ede2-0178-1000-dd20-22c2c827cbb7] Unable to unpack StandardFlowFileRecord[uuid=cfe7807c-d6ad-4127-b779-75b2f57c0ba6,claim=,offset=0,name=data.zip,size=0] due to org.apache.nifi.processor.exception.ProcessException: IOException thrown from UnpackContent[id=b746ede2-0178-1000-dd20-22c2c827cbb7]: net.lingala.zip4j.exception.ZipException: Could not fill buffer; routing to failure: org.apache.nifi.processor.exception.ProcessException: IOException thrown from UnpackContent[id=b746ede2-0178-1000-dd20-22c2c827cbb7]: net.lingala.zip4j.exception.ZipException: Could not fill buffer org.apache.nifi.processor.exception.ProcessException: IOException thrown from UnpackContent[id=b746ede2-0178-1000-dd20-22c2c827cbb7]: net.lingala.zip4j.exception.ZipException: Could not fill buffer at org.apache.nifi.controller.repository.StandardProcessSession.read(StandardProcessSession.java:2388) at org.apache.nifi.controller.repository.StandardProcessSession.read(StandardProcessSession.java:2333) at org.apache.nifi.processors.standard.UnpackContent$ZipUnpacker.unpack(UnpackContent.java:409) at org.apache.nifi.processors.standard.UnpackContent.onTrigger(UnpackContent.java:292) at org.apache.nifi.processor.AbstractProcessor.onTrigger(AbstractProcessor.java:27) at org.apache.nifi.controller.StandardProcessorNode.onTrigger(StandardProcessorNode.java:1173) at org.apache.nifi.controller.tasks.ConnectableTask.invoke(ConnectableTask.java:214) at org.apache.nifi.controller.scheduling.TimerDrivenSchedulingAgent$1.run(TimerDrivenSchedulingAgent.java:117) at org.apache.nifi.engine.FlowEngine$2.run(FlowEngine.java:110) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:515) at java.base/java.util.concurrent.FutureTask.runAndReset(FutureTask.java:305) at java.base/java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:305) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at java.base/java.lang.Thread.run(Thread.java:834) Caused by: net.lingala.zip4j.exception.ZipException: Could not fill buffer at net.lingala.zip4j.util.RawIO.readFully(RawIO.java:155) at net.lingala.zip4j.util.RawIO.readIntLittleEndian(RawIO.java:85) at net.lingala.zip4j.headers.HeaderReader.readLocalFileHeader(HeaderReader.java:529) at net.lingala.zip4j.io.inputstream.ZipInputStream.getNextEntry(ZipInputStream.java:85) at net.lingala.zip4j.io.inputstream.ZipInputStream.getNextEntry(ZipInputStream.java:77) at org.apache.nifi.processors.standard.UnpackContent$ZipUnpacker$1.process(UnpackContent.java:415) at org.apache.nifi.controller.repository.StandardProcessSession.read(StandardProcessSession.java:2365) ... 14 common frames omitted Maybe I do something wrong...
