Answer 1

I managed to solve this by doing the next:

In my flask app i added:

os.system("brownie run scripts/simple_collectible/create_collectible.py  --network rinkeby")

under my @app.route on flask.

The problem was that the code was running on the python CLI, and not in the Brownie CLI like it was supposed to.

It might not be the best way of doing it, but it works. Thanks
