Conditional jump or move depends on uninitialised value(s) after getline

Question

EDIT: I found the issue, the call of the function was a problem.

Item item = readItem(bookFile, world, item);

This is my code. Valgrind shows: Conditional jump or move depends on uninitialised value(s). It points at line: item.name(itemName); but when I debug itemName is assigned as expected (" NULL" in my case). What am I missing?

 Item readItem(std::ifstream &bookFile, World &world, Item& item) {
        std::string buffer;
std::string name, eName, itemName;
int itemStrength, itemChar, itemShield;

bookFile >> buffer;
if (buffer != "ITEM"){
    item.name("");
    return item;
}
getline(bookFile, itemName);

bookFile >> buffer;
if (buffer != "STRENGTH"){
    item.name("");
    return item;
}
bookFile >> buffer;
itemStrength = helpFunctions::stringToInt(buffer);

bookFile >> buffer;
if (buffer != "CHARISMA"){
    item.name("");
    return item;
}

bookFile >> buffer;
itemChar = helpFunctions::stringToInt(buffer);

bookFile >> buffer;
if (buffer != "SHIELD"){
    item.name("");
    return item;
}
bookFile >> buffer;
itemShield = helpFunctions::stringToInt(buffer);

if (itemStrength < 0 || itemChar < 0 || itemShield <0){
    item.name("");
    return item;
}

item.name(itemName);
item.strength(itemStrength);
item.charisma(itemChar);
item.shield(itemShield);

return item;
}

And Item class is this:

void Item::name(const std::string& name) {
      m_name = name;
}

void Item::strength(const int strength) {
    m_strength = strength;
}

void Item::charisma(const int charisma) {
    m_charisma = charisma;
}

void Item::shield(const int shield) {
    m_shield = shield;
}
