Hi team,
I’ve created a notebook for use as an interactive report and it runs fine in traditional/jupyter mode, but unfortunately when run in reactive mode, the kernel (python-minimal) consistently dies when a MongoClient (from the pymongo library) is created.
Code to recreate:
from pymongo import MongoClient
import os
client = MongoClient(os.environ['mongodb_address'], username=os.environ['mongodb_username'],
password=os.environ['mongodb_password'], authSource=os.environ['mongodb_db'])
Results in:
Traceback (most recent call last):
Error: The kernel has died
