Infinite loop

Infinite loop

[vhcsilva]

Hi, dzarezenko.
This is happening because the script executes while the messaging windows is open. So, even if user dont send something the script will check it.

I fixed it and did a pull request with the changes, that filters echos out and doesn't respond to them.

I am not sure this is a 'bug', but the contrary, something to be seriously solved.

It seems that it is linked with the following :
https://developers.facebook.com/docs/messenger-platform/faq

(quoting for reference) :

Why do I keep on getting developer alerts that my webhook has not been accepting updates, or keep getting the same webhook calls repeatedly?
Make sure your webhook is responding with a status code of 200. This communicates to us that the webhook was successfully received. If you do not return a 200, we will retry the call until successfully completed. Also, if a webhook doesn't return a 200 for an extended period of time, we will surface developer alerts.

Also, note that a successful status code is returned in a timely manner. A webhook call with timeout after 20 seconds. Be sure to architecture your code such that webhooks are processed asynchronously so that a successful status code can be returned immediately and processed separately.

and here, they describe the solution, but not sure how to implement it:
https://developers.facebook.com/docs/messenger-platform/webhook-reference#response

Your webhook callback should always return a 200 OK HTTP response when invoked by Facebook. Failing to do so may cause your webhook to be unsubscribed by the Messenger Platform.

It is extremely important to return a 200 OK HTTP as fast as possible. Facebook will wait for a 200 before sending you the next message. In high volume bots, a delay in returning a 200 can cause significant delays in Facebook delivering messages to your webhook.
A delivery receipt will automatically be sent to the user after your webhook has acknowledged the message. You can also use Sender Actions to notify that the message has been seen.

I am not sure that filtering out echos and ignoring them was the right solution.

What do you think ?
