    MessageHeaderAccessor headers = MessageHeaderAccessor.getMutableAccessor(originalMessage);
    if (originalMessage.getPayload() instanceof MessagingException) {
        headers.copyHeaders(MessageHeaderPropagation.propagationHeaders(additionalHeaders.getMessageHeaders(),
                this.tracing.propagation().keys()));
        return new ErrorMessage((MessagingException) originalMessage.getPayload(),
                isWebSockets(headers) ? headers.getMessageHeaders()
