Payload paramater in bot.on('postback', (payload, reply, actions)) is null

[chris247474]

Hi,

Not sure if its just me, but whenever I listen for a postback, the payload always returns null despite being assigned a value before the postback event triggers.

Whenever I use reply to echo the payload data to the user, I get an error message: Param message[text] must be a UTF-8 encoded string

bot.on('postback', (payload, reply, actions) => { reply({text: payload}, (err, info) => { if(err) { console.log(err.message) throw err } }) })

Unless I'm wrong and the payload object changes from a string before postback to a different object type?

Please advise guys
Thanks!

Sorry, my mistake. I took a closer look at the documentation and it was fine
