NameError: name 'os' is not defined

Reported by user @fjb80 (etiennesky#60):

When I try to export as a png, sag or dxf I get the following error:

NameError: name 'os' is not defined

How do I resolve this so I can export the profile?

Thanks,

We have not been able to reproduce your issue, but we have found a couple of apparently missing 'import os' statements in flowchart.py and plottingtool.py, will upload asap.
Could you provide the full error message (if you open the Python Console you should see the full stacktrace) to check that it is actually one of those two files that is at fault?

Here's the full error:

Hi @fjb80:
Thanks for the full trace! This should have been fixed with commit 7c98d69, we will be pushing an updated version to qgis repositories tomorrow.
If you want a quick fix before this gets published, you can manually add the line:
import os
to file /Users/USERNAME/Library/Application Support/QGIS/QGIS3/profiles/default/python/plugins/profiletool/tools/plottingtool.py right below 'import qgis'

Regards,
Javier

That did the trick as a quick fix. Thanks!
