I implemented your template and I ingested evtx files from my Windows 11 machine but the ParseEvtx processor did not parse the files. Kept getting the below error     03:52:24 UTC ERROR ParseEvx[id=19268a43-0189-1000-8d15-39df0b19faac] Processing failed: org.apache.nifl,processor.exception.ProcessException: [OException thrown from ParseEv[id=19268a43-0189-1000-8d15-39df0b19faac]: java.lo.I0Exception: Invalid minor version. Expected 1 got 2.     Can you please advise how to fix this ?   ... View more

  Here is the snapshot of the flow Getting data from an s3 bucket using ParseEvtx to parse it and forwarding data to Splunk via Splunk's HEC protocol   There wasn't much to configure in ParseEvtx other than the granularity which is set to "Chunk"   I then attempted to add sample data from this link - https://github.com/apache/nifi/raw/rel/nifi-1.0.0/nifi-nar-bundles/nifi-evtx-bundle/nifi-evtx-processors/src/test/resources/application-logs.evtx which is provided within this forum post https://community.cloudera.com/t5/Community-Articles/Parsing-evtx-files-with-Apache-NiFi/ta-p/247550 and that evtx file was successfully parsed by the processor. ...

Unable to get FetchS3Object using an IAM role

I have NiFi installed on an EC2 instance   NiFi version - 1.22.0   I have a requirement to pull files text files from s3 bucket and write them locally in NiFi as PoC.   I have configured an input_port and FetchS3Object and PutFile processor as shown in the screenshot. The Nifi ec2 intance already has access to the s3 bucket and I have checked that by using "aws s3 cp s3_uri ./" command to copy files from s3 bucket to ec2 instance and it worked, However, for some reason, it seems NiFi FetchS3Object processor is running into some issue.   The Nifi-app.log havent been very helpful even though I enabled "debug" level on the processor. It showed no error or warn messages. The only messages the processor showed is on the gui as shown in the screenshot.   I have shown the values I configured in configuration. Only specified bucket name, object key, which I initially set to *.evtx but then changed to * to get any file and region option. Did not specify access key or secret as using the IAM roles associated with the EC2, which already has access to the s3 bucket, the processor should be able to pull the files.   Can anyone please help how I can fix this issue ? ...
