How to reproduce: Build a transaction with ~190 inputs, get the hex and issue `testmempoolaccept [\"{txhex}\"]` in the GUI console. It'll give back a `TX decode failed (code -22)` with a stripped txhex where the end is cut down.
ui->startupTime->setText(model->formatClientStartupTime());
        ui->networkName->setText(QString::fromStdString(Params().NetworkIDString()));
        //
        QStringList wordList;
        std::vector<std::string> commandList = m_node.listRpcCommands();
        for (size_t i = 0; i < commandList.size(); ++i)
        {
            wordList << commandList[i].c_str();
            wordList << ("help " + commandList[i]).c_str();
        }
        wordList << "help-console";
        wordList.sort();
        autoCompleter = new QCompleter(wordList, this);
        autoCompleter->setModelSorting(QCompleter::CaseSensitivelySortedModel);
