Hi all, I followed these instructions to the letter (https://developers.facebook.com/docs/messenger-platform/getting-started/webhook-setup) but I keep getting this error! What am I doing wrong?

Requesting side>>>

This works: curl -X GET "localhost:1337/webhook?hub.verify_token=999999999999999&hub.challenge=CHALLENGE_ACCEPTED&hub.mode=subscribe"

But not this: curl -H "Content-Type:application/json" -X POST "localhost:1337/webhook" -d '{"object": "page", "entry": [{"messaging": [{"message": "TEST_MESSAGE"}]}]}'

issue can be reproduced when pushed up to Heroku and run in a production environment

node@8.9.4 npm@5.6.0 body-parser@1.18.2 express@4.16.2

express and body-parser installed via: npm install express body-parser --save

same issue as:

I'm starting to figure out that the actual code in the app works just fine. Everything parses fine, post and get work fine. It's something to do with the command line curl command. I was able to move on and create a successful messenger bot. That's probably why the two other guys just stop responding to their thread. This can be closed.

Hello @ marketingstarz I'm creating my webhook for my Messenger bot but i'm having the same issue as you have:

But not this: curl -H "Content-Type:application/json" -X POST "localhost:1337/webhook" -d '{"object": "page", "entry": [{"messaging": [{"message": "TEST_MESSAGE"}]}]}'

Shoot "Theojs-bit". I'm very sorry. It's been so long that I don't remember the solution.

Check this link. This worked for me when I was having the same issue. Something to do with escaping quotes on Windows on the curl command.

This is the code I have used instead of the one on the guide from Facebook.

curl -H "Content-Type: application/json" -X POST "localhost:1337/webhook" -d {\"object\":\"page\",\"entry\":[{\"messaging\":[{\"message\":\"TEST_MESSAGE\"}]}]}

If you want to compare, here's the code from Facebook's guide when I am posting.

curl -H "Content-Type: application/json" -X POST "localhost:1337/webhook" -d '{"object": "page", "entry": [{"messaging": [{"message": "TEST_MESSAGE"}]}]}'
