Use a 'debug' node connected to the flow before the node causing the error. Configure the 'debug' node to display the `msg.payload` and `msg.length` (or `Buffer.byteLength(msg.payload)` for buffers). This will show you the actual size of the payload being sent, helping you pinpoint where the large data is originating.
