No message response

[nanthanwa]

in web hook router

const promises = req.body.events.map(event => { return line.client .replyMessage({ replyToken: event.replyToken, messages: [ { type: 'text', text: event.message.text } ] }) }) Promise .all(promises) .then(() => res.json({success: true}))

It should echo the message but nothing and without any error :(

you should need signature header.
When I try to execute command, I got following errors instead.
