Node File not creating or appending file

Hi I've been using the Nodered plugin in Hassio for a while works great I have quite a few flows running.

I would like to log MQTT payloads to a file.
To test I send a simple timestamp to the File Node.
(Standard File Node node-red0.20.3)
No errors are reported but the file is not created or if I manually create it, it is not written to.
The Directory exists on the Pi. I monitor it using Filezilla.

HassOS 2.8 shows I have Version Nodered 2.0.2 installed . Also says 4.01 while available is not compatible with my system so I can't update at this point.

If I try and enter an invalid file path in the File Node I get an error message saying directory doesn't exist and it does not complain when I use the correct path so seems it can see the file location.

Does anyone have a suggestion on what I could try.

Simple Flow is shown below.

You might want to try the new flogger node?

Thanks for the suggestion but had the same result . File not created. Existing file not appended too.

Have you checked permissions on that folder and the file? Is it owned by the pi user or root?

The whole thing was built using the installer onto a pi, then has a plugin for Nodered so I assumed it would own the files but as you suggest it's worth checking. When I putty into the pi I just see the CLI which I cant figure out how to exit. The Command line doesn't seem to recognize simple linux commands like 'ls' . Is there a way to exit this view. Sorry might be a better question for the community.

Yes, sorry I think that you would be better off asking there.
