Hi all,
We are developing a use case in which we have to get some files from a
server. We have implemented it by the listSFTP + FetchSFTP way in a 3 nodes
cluster running nifi 1.15.3. But we are having some issues when what
we want to get are symlinks instead of files. We have set true the
property *"Follow
symlink" *but we get the same results. Are we doing something wrong? Or is
it a bug or a known issue? We have found this issue [1] but it is old and
resolved and this other one [2], that is older and unresolved. We're not
sure if they are related to this behaviour or not.
I paste our error log:
