No output with testinvoke

[zioalex]

Hi Dann! Thanks a lot for this talk really interesting. I followed it very carefully trying to mimic what you did. I created the smartcontract but when I use testinvoke I do not see the output coming from the compiled code. Can you help with it? Also which app are you using to see the privnet wallet?

I just report here the commands done:

docker pull cityofzion/neo-privatenet
docker run --rm -d --name neo-privatenet -p 20333-20336:20333-20336/tcp -p 30333-30336:30333-30336/tcp cityofzion/neo-privatenet

docker exec -it neo-privatenet /bin/bash
rm -rf /root/.neopython/Chains/privnet/
neopy
create wallet privnet1
pw: neocamp2018
import wif KxDgvEKzgSBPPfuVfw67oPQBSjidEiqTHURKSDL1R7yGaGYAeYnr
open wallet privnet1

I cannot figure out the problem. Do you have any idea? Which tools can I use to debug it?
