In my NiFi workflow I need to download .zip file from SOAP web-server, save it on machine (optional) and unpack content to sub-folder. Everything works on my local Win 10 machine, but issues occur when I try to move to remote Linux server. Here is the part of my flow when error happens:
So we have a FlowFile entered UpdateAttribute where filename attributed is set with required name and .zip extension. The file is correct as can be seen in queue after starting the processor.
Problems start happen when I pass the FlowFile to PutFile processors. I tried different scenarios based on selected directory:
relative to NiFi main folder ./out:

So it adds dot ('.') to path which causes exception. All folders are created and permissions granted. I tried to run simple test flow with file of 42B and the same path (GenerateFlowFile -> PutFile) and everything is OK.
What am I doing wrong?
