Why triggering sendText endpoint from other process cause 500 error {"stack":"TypeError: Cannot read properties of undefined (reading 'includes') ...

I was able to run WAHA docker container and it can be run successfully using Postman and CURL. But when I wrap it to Python and trigger it using python requests aiohttp it gives me 500 error? Where is my mistake?

Using requests library

import requests
r = requests.post(
    "http://localhost:3000/api/sendText",
    json={
        "clientId": "<RECEPIENT>",
        "text": "Hello World!",
        "session": "default",
    },
)
print(r.text)

Using aiohttp

import aiohttp
import asyncio


async def main():

    async with aiohttp.ClientSession() as session:

        target_url = "http://localhost:3000/api/sendText"

        async with session.post(target_url, json=DATA) as resp:
            json_resp = await resp.json()
            print(json_resp)
asyncio.run(main())

Both result:

{"statusCode":500,"timestamp":"2025-01-13T09:11:13.547Z","exception":{"stack":"TypeError: Cannot read properties of undefined (reading 'includes')\n    at ensureSuffix (/app/dist/core/abc/session.abc.js:27:15)\n    at WhatsappSessionNoWebCore.ensureSuffix (/app/dist/core/abc/session.abc.js:392:16)\n    at WhatsappSessionNoWebCore.sendText (/app/dist/core/engines/noweb/session.noweb.core.js:401:35)\n    at ChattingController.sendText (/app/dist/api/chatting.controller.js:30:25)\n    at process.processTicksAndRejections (node:internal/process/task_queues:105:5)","message":"Cannot read properties of undefined (reading 'includes')","name":"TypeError"},"request":{"path":"/api/sendText","method":"POST","body":{"clientId":"<SOMEONE>@c.us","text":"Hello World!","session":"default"},"query":{}},"version":{"version":"2025.1.3","engine":"NOWEB","tier":"CORE","browser":"/usr/bin/chromium"}}

Hi! it's chatId, not clientId

import requests
r = requests.post(
    "http://localhost:3000/api/sendText",
    json={
        "chatId": "123123",
        "text": "Hello World!",
        "session": "default",
    },
)
print(r.text)

We need to add better error message, you're right about that, thank you!
