My goal: use localStorage API to a credential for my internal API that can be re-used when the page reloads. Issue: My app was working previously. Today I see: “localStorage.getValue is not a function”. I do not see the function mentioned in the localStorage docs online, so I am wondering if it was…

I changed to localStorage.values.adminBearerToken instead which I see is an alternative syntax and this works for me now. It’s curious getValue() was working when I built the app on Thursday, then today it was not working. Version is 3.291.0, same as the screenshot you sent.

Can you confirm that this is still an issue for you, @Jacob_Muchow? I'd be interested in taking a look during Office Hours, if you're able to join.
