Environment

Pythonnet version: 3.0.3
Python version: 3.10, 3.11, 3.12
Operating System: Linux (Ubuntu 22.04)
.NET Runtime: 8.0, 7.0, 6.0

Details

I have a web app I am trying to deploy on AWS which uses .NET to communicate with a vendors API. I have tried a lot of different things, reordering calls, uninstalling and reinstalling, calling it separately, but I am just lost. I thought it was possibly environmental variable but it doesnt seem to be that either

TODO
I just call pythonnet load() and use clr (which works locally on my windows 10 work PC but not on a linux server or my linux PC at home).

import pandas as pd
import sqlite3 as sql
import json
from pythonnet import load
load('coreclr')
import clr

# Python .NET interface ----------------------------------------------------
sys.path.append('PLEXOS 10.0 API')
clr.AddReference('PLEXOS_NET.Core')
clr.AddReference('EEUTILITY')
clr.AddReference('EnergyExemplar.PLEXOS.Utility')
