I am trying to create an OAuth chatbot . While the app is being added , the default chatbot message is : **Unsupported type of message**. I am trying for custom Welcome message , default message didnt work as well . I am seeing response 200 for the webhook endpoint .

I am using FastAPI library in Python for the webhook . My code looks something like this .

```auto
@app.webhooks.post("/welcome-webhook")
async def handle_zoom_webhook(payload: WebhookPayload):
    robot_jid = payload.payload.get("robotJid")
    user_jid = payload.payload.get("userJid")
    user_name = payload.payload.get("userName")
    account_id = payload.payload.get("accountId")

    response_payload = {
        "robot_jid": robot_jid,
        "to_jid": user_jid,
        "account_id": account_id,
        "content": {
            "head": {
                "text": f"Welcome {user_name}!"
            },
            "body": [{
                "type": "message",
                "text": "Thank you for installing the bot. How can I assist you today?"
            }]
        }
    }

    return JSONResponse(content=response_payload, status_code=200)

```

Hi @venketesh.andavarapu  
Thanks for reaching out to us and welcome to the Zoom Developer Forum!  
Have you been able to troubleshoot this on your end? or still getting the Unsupported type of message error when adding your chatbot?
