Stuck on this: OSError: [Errno 8] Exec format error: '/tmp/ngrok/ngrok'

Any idea why I'm getting this error with a basic test script?
i'm running the script as:
sudo python3 flaskngrokdemo.py

raspberry pi zero (not 64bit, maybe the problem?)

Any updates on this? Getting the same error on my Raspberry Pi 3B+, I have installed flask-ngrok===0.0.26 on a virtual environment and I am running the script without sudo.

[EDIT] Figured it out. Check #30
