What happened?

Steps to reproduce:

• create a pipeline that generates a recordset with the fields requested by the Move files action: you can simply add a Data grid (with the fields src_path, dst_path and wildcard, and respective values) and link it with a Copy rows to result
• create a workflow that uses the above pipeline and link it to a Move files action
• in the Move files action, check "Copy previous results to args" and "Destination is a file"

When dealing with local files, the action fails with the following error:

2024/06/12 10:01:33 - Move files - found [1] argument(s) from previous result
2024/06/12 10:01:33 - Move files - Processing row source File/folder source : [/work/hop/mount/iraiser/in/expIraiser_2024_06_07.csv] ... destination file/folder : [/work/hop/mount/iraiser/in/_deleteme_expIraiser_2024_06_07.csv]... wildcard : [null]

2024/06/12 10:01:33 - Move files - =======================================
2024/06/12 10:01:33 - _stub-move-files - Finished action [Move files] (result=[false])

When dealing with remote files (like those in an sFTP server), Hop throws an Exception: it cannot print an error because a variable destinationfilefolder is null (see #3985 for the log trace).

In both cases, the Detailed log (example above) shows that the file names and the (empty) wildcard are correctly passed from the pipeline to the Move files action
