Failed to invoke Symbol Storage.deleteValue()

I'm am executing the following code

// Request access token and refresh token in exchange for authorisation code
    var codeVerifier = Storage.getValue("codeVerifier");
    // Only persisted to length of exchange
    Storage.deleteValue("codeVerifier");

The last action to delete the key from Storage is failing with

Error: System Error

Anyone come across this before. Is it trying to tell me I can't delete the Storage key because I have a local variable that somehow is locking it because the Storage.getValue() in the previous line?

When you do the deleteValue() are you sure the key actually exists in storage? Could be this is happening with new users when there was never a setValue for that key.

maybe do a getValue on it first and check that doesn't return null before the deleteValue

Absolutely it exists in storage.

Okay I’ve got to bottom of this as I’ve had same behaviour on an another unrelated datafield I’m developing. I’ve been able to replicate it consistently. It is a IQ bug, and I’ve raised a report.

Today a Beta software relase for Edge 1040 series was announced, stating (amongst others):

Fixed crash when entering mass storage.
