Hi @Colin7 ,
This looks like an error resulting from Heron not finding the proj.db file needed for GDAL’s coordinate transformations. Does the output from the GDAL Details component give you a list of drivers?
If not, try loading Heron from disk as described here:
Hi @Dongyeop_Lee ,
I have seen this happen when installing Heron through the package manager, which is the preferred method (related Heron Github issue ). Basically, Heron is looking for GDAL libraries and can’t find them when they are installed in the packages folder. The work-around for this issue has been the following: in Grasshopper Settings>Solver>Plug-in Loading, scroll down to Heron and click the little puzzle piece icon so that you see the disk.

I have found a possible fix …
Or turning off COFF as described here:

I am not familiar at all with this setting, so I might I have said something wrong.
The checkbox highlighted in the image above was ON for me by default, and I guess that particular default setting is the same for everyone. I think it applies to the library folder, therefore to all plug-ins. After unchecking the box, I could make Opennest work without any trouble.
