René Zeidler commented on NIFI-5894:
------------------------------------
I encountered the same NPE on NiFi 1.23.2 using a PutFTP processor:
{code:java}
java.lang.NullPointerException: Cannot invoke
"java.util.Calendar.getTimeInMillis()" because the return value of
"org.apache.commons.net.ftp.FTPFile.getTimestamp()" is null
