POST /api/v2/conversations/messaging/contacts/{contactId}/messages returns 400 Bad Request. The error message says Invalid message type for channel. Here is the JSON body we are sending via the Node SDK:
{
"content": {
"quickReplies": [
{
"title": "Option 1",
"value": "opt1"
}
]
}
}
The contact is active and the channel is web. The API docs say this structure is valid for web messaging. Are we missing a required field in the content object?
