`${SERVER_URL}/` seems to be not resolving properly

@schvenk @tcsapunaru

my code can be found https://github.com/RohitBansal18/chatbot

This is not a issue in the sample example bot. I am creating new bot and following example step by step but stuck at GET_STARTED only. pls help.

It looks like you are using straight quotes instead of backticks. Your code has '${SERVER_URL}/' If you want to use ES6 template strings, you need to use backticks instead of straight quotes.

Thanks @amuramoto for replying. However, I was using backticks only in original code and I tried again, it is giving same error.

I found at URL: https://github.com/pimax/fb-messenger-php-example/issues/27 This error can be because of other issues which are not directly pointed out in logs

Looking at this it would seem the message is not well formed: Successfully sent message to messages endpoint: {"recipient_id":"1493046944115720"} If that's not it can you put a console log and JSON stringify the exact payload you are sending to the graph API?

@tcsapunaru I started using "messenger profile" endpoint instead of "thread settings" endpoint for Domain White Listing, GET_STARTED, etc. now it works fine.

thanks all...closing issue it is working fine now.
