Guille, I did a quick test on my MacBook and things worked as expected following symlinks. If I set the property to “false” it didn’t get the files. If I set it to “true” it did retrieve the files. Either way it didn’t error, though - just didn’t follow the symlink.
Of course, that’s not to say that there’s not some issue, just that it’s not obviously always broken :) One thing that I notice in the log message there, though: "Could not perform listing on testfile.gz…” There are a couple of spaces there - it’s not looking for “testfile.gz” but rather “<space><space>testfile.gz” - are there actually spaces in the filename? Or any other sort of character there, that is perhaps not being properly escaped?

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.
