I'm trying to work with the WhatsApp business API, but When I try to send a message, always gives me this error with http code 400:

"message": "(#100) Tried accessing nonexisting field (messages) on node type (WhatsAppBusinessPhoneNumber)",

URL:

https://graph.facebook.com/v17.0/NUMBER_ID/messages?access_token=**ACCESS_TOKEN** 

Body:

{     "messaging_product": "whatsapp",     "to": "5**39&&&&&&1",     "type": "template",     "template": {         "name": "hello_world",         "language": {             "code": "en_US"         }     } } 

Response:

{     "error": {         "message": "(#100) Tried accessing nonexisting field (messages) on node type (WhatsAppBusinessPhoneNumber)",         "type": "OAuthException",         "code": 100,         "fbtrace_id": "Ai8BDTgVwlWuJo6QeTmqRB7"     } }

When connecting to Whatsapp Cloup Api, The following webhooks can't be subscribed:
Message_echoes Messaging_handovers

I am a tech provider developing a Whatsapp Integration that has the following flow:
User signs up on our platform using the Whatsapp Embedded Signup
After the sign up is complete, we retrieve the user's access token (after exchanging it for the code).
We use the user's access token to retrieve his business ID
We subscribe the business ID to a unique webhook URL
We listen for new whatsapp messages on the webhook URL and respond to the messages
Currently, we have steps 1 - 4 working. Step 5 is not working because even after subscribing to the webhook URL and receiving a success: true, sending messages to the phone number of the Whatsapp Business Account does not trigger webhook notifications on the webhook URL.
I have read all of the documentation regarding webhooks and I can't seem to find anything. I would greatly appreciate any support and can provide details if necessary.
