Metadata Issue in Hosted Chat Trigger with File Upload and Authentication

Hi n8n team,

I’m currently using the hosted Chat Trigger node with n8n authentication enabled.

When a user sends a message along with a file upload, I can see the file is received, but the metadata attached to the message shows as:

metadata: [object Object]

It seems like the object is not being properly serialized, and I can’t access the actual data inside it (like user info, session, etc.). I was expecting metadata to include user identification or auth context, especially since I’m using authenticated chat.

Is this expected behavior? If not, could this be a bug or a limitation of the current chat implementation?

Let me know if you need logs or a reproducible example.

Thanks in advance!
