Error: Cannot create a stable subkey under a volatile parent key

I am getting below error in javascript in IE 11 on Windows 7.

Error: Cannot create a stable subkey under a volatile parent key.

        if (window.localStorage.getItem('toCurrencyCode') == null || window.localStorage.getItem('toCurrencyCode') == 'undefined' || window.localStorage.getItem('toCurrencyCode') == '') {
            dataLayer.push({ 'chosenCurrencyCode': defaultCurrencyConversionCode });

My understanding is coming that javascript is not able to read window.localStorage.getItem on IE 11 on windows 7.

The script is working on chrome, firefox, IE11 on windows 10

Also, script is working on chrome on windows 7.

It is only giving issue in IE11 on windows 7.

Please advise.

If you compare the IE11 settings in both environments (Win7 and Win10), is there a difference with regard to the security zones? Is Protected Mode enabled on both?

The error message itself is caused by the Windows registry. Is your Windows 7 and IE11 properly patched?

Imho the error is caused in dataLayer.push(), which seems to be a custom method.


 Restoring IE to default setting helped.
