Issue Description
Cannot download media from WhatsApp Business accounts (@lid). Calling message.downloadMedia() throws TypeError: Cannot read properties of undefined (reading 'split') internally inside downloadBuffer (or similar inner functions). Regular @c.us media works perfectly, only @lid media fails.
Reproduction Steps
- Receive an image, video or audio from a WhatsApp Business account (
@lid contact).
- Call
await message.downloadMedia() on that message.
- Observe the
Cannot read properties of undefined (reading 'split') error being thrown inside wwebjs.
Code Sample
client.on('message', async (message) => {
if (message.hasMedia && message.from.includes('@lid')) {
try {
const media = await message.downloadMedia();
} catch (err) {
console.error(err); // Throws the 'split' error
}
}
