I'm really no expert in this domain, so just doing some educated guessing.<br>

First of all, the importgrass.py you sent only has 72 lines, so I don't <br>
know what the line 82 reference in your above error points to.</div>

But most importantly, I would really recommend that you upgrade to a <br>
newer version of GRASS GIS. Current stable is 7.8. There's been a lot of <br>
improvement in terms of python3 compatibility and maybe this is an issue <br>
that has already been resolved.<br>
<br>
It sounds like an issue with a variable containing a path. Apparently it <br>
is of type NoneType...</div>

What happens when you replace '/usr/bin/python3 importgrass.py ' by, for <br>
example '/usr/bin/grass --version', just to check if other executables <br>
work ?</div>
