We have the same issue

Hi!
How large is the video file?
Do you have sufficient CPU and memory resources?
Does the option to "log out and scan the QR code" help?
Are there any errors in the Docker logs?

Tienes toda la razón, si quieres que realmente entienda por qué a ti sí te funciona y a él no, lo mejor es mostrarle el payload (el cuerpo de la solicitud) que estás enviando.

"Hi @DidiDerDenker,

I'm currently using version 2026.3.3 (WEBJS - PLUS) and /api/sendVideo is working correctly for me when sending to Channels.

The ProtocolError: Runtime.callFunctionOn timed out usually happens when the browser (Puppeteer) takes too long to process the file. Here is how I'm sending the request in Python, which might help you compare with your implementation:
JSON

{
"chatId": "120363XXXXXXXXXXXX@newsletter",
"file": {
"mimetype": "video/mp4",
"data": "BASE64_DATA_HERE...",
"filename": "video.mp4"
},
"caption": "Your creative text here",
"convert": true
}

A few things to check:

convert: true: This is essential for compatibility.

Base64 vs URL: I'm using Base64 directly. If you are using a URL, the timeout might be happening while WAHA downloads the file.

Request Timeout: Make sure your HTTP client (where you run the script) has a timeout of at least 120 seconds. If your client closes the connection at 30s but WAHA is still processing, you might see these errors.

Server Resources: Processing video via WEBJS is CPU intensive. If your server is low on resources, Puppeteer will time out.

I hope this helps you debug your environment!"
