SyntaxError: Unexpected token robot.http when create new js to http request

[Ivan Martin Perez Kranilovich]

Hi, I write hubot script in javascript.
I want to create a hubot function to send post http to a webhook.

module.exports = (robot) => {
robot.respond(/resume (.*)/i, (res) => {
text = res.match[1]
data = JSON.stringify({ json: '{"id": ${text}}'})
robot.http("https://stackstorm/api/v1/webhooks/resume_workflow")
.header('Content-Type', 'application/json')
.header('PRIVATE-TOKEN', 'xxxxxx')
.post(data) (err, res, body) =>
if err
res.send "Encountered an error :( #{err}"
return
})
}

But when run hubot I get the next message:
