Uncaught Error: toString failed

I'm getting this error when trying to print a (rather large) variable. After the error, trying to run other lines gives a checkmark but no actual output.

Message::_decode can throw this error.

Message::on wraps message listeners with a callback that invokes calls Message::_decode.

Message::once wraps message listeners with a callback that invokes calls Message::_decode.

Message::_encode creates buffers.

Message::send calls Message::_encode.

At the moment, I'm inclined to work around this issue by wrapping the body of Message::_decode in a try-catch block and return null if an exception of this kind is thrown.
