Smooch: How to do postback dependent state transition?

Question

I am trying to transition the script from one state to another based on Smooch postback payloads; but getting error code H12.

Consider the example https://github.com

Postbacks won't automatically transition your conversation from one state to the next, you have to write that logic yourself. Luckily the smooch-bot-example you're using already has a postback handler defined here:

https://github.com/smooch/smooch-bot-example/blob/30d2fc6/heroku/index.js#L115

So whatever transition logic you want should go in there. You can do this by creating a stateMachine and calling receiveMessage() on it the same way handleMessages() already works. For example:

const stateMachine = new StateMachine({
    script,
    bot: createBot(req.body.appUser)
});

stateMachine.receiveMessage({
    text: 'whatever your script expects'
})

Alternatively, you could have your handlePostback implementation call stateMachine.setState(state) and stateMachine.prompt(state) independently, if you wanted to have your postbacks behave differently from regular text responses.
