Hi, I'm having a NiFi error when I try to download a file. Especially in the InvokeHttp process. The error does not always appear for the uuid itself. 2017-05-12 12:45:11,034 ERROR [Timer-Driven Process Thread-42] o.a.nifi.processors.standard.InvokeHTTP InvokeHTTP[id=d5ee3432-122a-133t-a3e2-4c7233ds4500] Routing to Failure due to exception: org.apache.nifi.processor.exception.FlowFileAccessException: Failed to import data from buffer(com.squareup.okhttp.internal.http.Http1xStr eam$FixedLengthSource@2e12123).inputStream() for StandardFlowFileRecord[uuid=33482899-3ddc-2441-c73e-3dd2838ss929,claim=,offset=0,name=Process_00123.zip,size=0] due to org.apache.nifi.processor.exception.FlowFileAccessException: Unable to create ContentClaim due to java.net.ProtocolException: unexpected end of stream: org.ap ache.nifi.processor.exception.FlowFileAccessException: Failed to import data from buffer(com.squareup.okhttp.internal.http.Http1xStream$FixedLengthSource@2e12123).i nputStream() for StandardFlowFileRecord[uuid=33482899-3ddc-2441-c73e-3dd2838ss929,claim=,offset=0,name=Process_00123.zip,size=0] due to org.apache.nifi.processor. exception.FlowFileAccessException: Unable to create ContentClaim due to java.net.ProtocolException: unexpected end of stream 2017-05-12 12:45:11,124 ERROR [Timer-Driven Process Thread-42] o.a.nifi.processors.standard.InvokeHTTP org.apache.nifi.processor.exception.FlowFileAccessException: Failed to import data from buffer(com.squareup.okhttp.internal.http.Http1xStream$FixedLengthSource@2e12123).inputStream() for StandardFlowFileRecord[uuid=33482899-3ddc-2441-c73e-3dd2838ss929,claim=,offset=0,name=Process_00123.zip,size=0] due to org.apache.nifi.processor.exception.FlowFileAccessException: Unable to create ContentClaim due to java.net.ProtocolException: unexpected end of stream at org.apache.nifi.controller.repository.StandardProcessSession.importFrom(StandardProcessSession.java:2690) ~[na:na] at org.apache.nifi.processors.standard.InvokeHTTP.onTrigger(InvokeHTTP.java:700) ~[nifi-standard-processors-1.1.0.2.1.0.0-165.jar:1.1.0.2.1.0.0-165] at org.apache.nifi.processor.AbstractProcessor.onTrigger(AbstractProcessor.java:27) [nifi-api-1.1.0.2.1.0.0-165.jar:1.1.0.2.1.0.0-165] at org.apache.nifi.controller.StandardProcessorNode.onTrigger(StandardProcessorNode.java:1099) [nifi-framework-core-1.1.0.2.1.0.0-165.jar:1.1.0.2.1.0.0-165] at org.apache.nifi.controller.tasks.ContinuallyRunProcessorTask.call(ContinuallyRunProcessorTask.java:136) [nifi-framework-core-1.1.0.2.1.0.0-165.jar:1.1.0.2.1.0.0-165] at org.apache.nifi.controller.tasks.ContinuallyRunProcessorTask.call(ContinuallyRunProcessorTask.java:47) [nifi-framework-core-1.1.0.2.1.0.0-165.jar:1.1.0.2.1.0.0-165] at org.apache.nifi.controller.scheduling.TimerDrivenSchedulingAgent$1.run(TimerDrivenSchedulingAgent.java:132) [nifi-framework-core-1.1.0.2.1.0.0-165.jar:1.1.0.2.1.0.0-165] at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) [na:1.8.0_111] at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:308) [na:1.8.0_111] at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(ScheduledThreadPoolExecutor.java:180) [na:1.8.0_111] at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:294) [na:1.8.0_111] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) [na:1.8.0_111] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) [na:1.8.0_111] at java.lang.Thread.run(Thread.java:745) [na:1.8.0_111] Caused by: org.apache.nifi.processor.exception.FlowFileAccessException: Unable to create ContentClaim due to java.net.ProtocolException: unexpected end of stream at org.apache.nifi.controller.repository.StandardProcessSession.importFrom(StandardProcessSession.java:2683) ~[na:na] ... 13 common frames omitted Caused by: java.net.ProtocolException: unexpected end of stream at com.squareup.okhttp.internal.http.Http1xStream$FixedLengthSource.read(Http1xStream.java:396) ~[okhttp-2.7.1.jar:na] at okio.RealBufferedSource$1.read(RealBufferedSource.java:371) ~[okio-1.6.0.jar:na] at java.io.InputStream.read(InputStream.java:101) ~[na:1.8.0_111] at org.apache.nifi.stream.io.StreamUtils.copy(StreamUtils.java:35) ~[nifi-utils-1.1.0.2.1.0.0-165.jar:1.1.0.2.1.0.0-165] at org.apache.nifi.controller.repository.FileSystemRepository.importFrom(FileSystemRepository.java:700) ~[na:na] at org.apache.nifi.controller.repository.StandardProcessSession.importFrom(StandardProcessSession.java:2680) ~[na:na] ... 13 common frames omitted Any idea what would cause this exception, and how to fix it? ...
