I followed the Viber Python Bot Tutorial to create a bot:
https://developers.viber.com/docs/api/python-bot-api/
I have deployed a local server using Ngrok, following this tutorial:
https://developers.viber.com/blog/2017/05/24/test-your-bots-locally
My problems:
When I try to call the set_webhook API method with the url provided by Ngrok, I get this error:
Exception: failed with status: 999, message: DB Failure
What can I do to fix that?
From what I understand I can use this bot to send messages to Viber users who have subscribed to this bot.
How can a user subscribe to my bot? I can see the bot in my messages tab, but I can't subscribe or send a message to it.
