[ISSUE] Deploying on heroku won't set webhook

[vinicius507]

I've built a Messenger Bot and deployed it on Heroku.
I set all environment variables and Procfile, but can't get it to set webhook.
Here's the error:

✖ Failed to set Messenger webhook

✖ status: 400

✖ data: {

  "error": {

    "message": "Error validating application. Cannot get application info due to a system error.",

    "type": "OAuthException",

    "code": 190,

    "fbtraceId": "AYvMEf97oww2UfYYRrZgTUY"

  }

}

I'm using bottender 1.4.10.

There was a misspelling in Procfile. Closing.
