Hi All,

I’ve been testing my app on the thunkable compnent and it works fine, I go to download the app or publish the app and I am receiving the below error on loading - is this a known bug from the recent update? It was working before this,

Hi, @jacob1! 👋

The message says it clear, that you are storing a `null` value in `Local Storage` -

It would be helpful if you could you show us your blocks…

Thanks! 😊

Thanks for your reply @kartik14

I have checked and tested the variable ChACC1 is being populated so I don’t see how this would be null
