How to sort files by filename: read binary files -> sort

How to sort a file list from a read binary files node

What is the error message (if any)?

When using the sort node with code some times I get the error “ERROR: Sort code doesn’t return. Please add a ‘return’ statement to your code”.
I say some times because I’m pretty sure it works some times.
The default code in the sort Node does not work with read binary files output so I changed it.
Also I can’t find the correct syntax to use the “normal” sort operation. Can’t input the correct fieldname.

Please share your workflow

Share the output returned by the last node

Hi @Duarte_Carreira :wave: Would you be able to provide an example file we could use for testing on this one for you?

Hey, I’ve just now solved the issue, kind of…

I had a workflow made on a pre-v1.0 that kept working fine after upgrading recently to 1.x. Or s I thought…

I suspect it never did run properly but I never got an error running through a webhook.

I rebuilt the workflow now, in the process I’ve put some logic in a sub-workflow. I used a code node to sort the files:

My filenames are like these:

They are plain text files.

So at this moment everything is running fine, files are downloading from an ftp server, and ingested to postgresql.

I couldn’t figure out exactly what I solved…
