I'm having this problems and by logging the error is leading to these functions

void ProtocolGame::updateCoinBalance()
{
    NetworkMessage msg;
    msg.addByte(0xF2);
    msg.addByte(0x00);
    writeToOutputBuffer(msg);
    g_dispatcher.addTask(
        createTask(std::bind([](ProtocolGame_ptr client) {
        client->sendCoinBalance();
    }, getThis()))
    );
}
void ProtocolGame::sendCoinBalance()
{
    Database& db = Database::getInstance();
    std::ostringstream query;
    query << "SELECT `coins` FROM `accounts` WHERE `id`=" + std::to_string(player->getAccount());
    DBResult_ptr result = db.storeQuery(query.str());
    if (!result) {
        return;
    }
    NetworkMessage msg;
    msg.addByte(0xF2);
    msg.addByte(0x01);
    msg.addByte(0xDF);
    msg.addByte(0x01);
    msg.add<uint32_t>(result->getNumber<uint32_t>("coins")); //total coins
    msg.add<uint32_t>(result->getNumber<uint32_t>("coins")); //transferable coins
    writeToOutputBuffer(msg);
}
