Failed to execute 'setItem' on 'Storage': Setting the value of 'state' exceeded the quota (localStorage.clear() won't work)

Question

In my React project I use Redux where I save the serialized state:

const saveState = (state: any) => {
    try {
        const serializedState = JSON.stringify(state);

        localStorage.removeItem('state');
        localStorage.clear();
        localStorage.setItem('state', serializedState);

    } catch (e) {
        console.log(e);
        let _lsTotal = 0, _xLen, _x; for (_x in localStorage) { if (!localStorage.hasOwnProperty(_x)) { continue; } _xLen = ((localStorage[_x].length + _x.length) * 2); _lsTotal += _xLen; console.log(_x.substr(0, 50) + " = " + (_xLen / 1024).toFixed(2) + " KB") }; console.log("Total = " + (_lsTotal / 1024).toFixed(2) + " KB");
    }};

Since I came upon the 'Setting the value of 'state' exceeded the quota' error I tried to clear the local storage (see above). Yet I still get this error, and the code in the catch part shows 0.00KB of the storage:

DOMException: Failed to execute 'setItem' on 'Storage': Setting the value of 'state' exceeded the quota.

How to avoid this error?
