Hi,
My lightning component and apex class are not a part of managed package and they are public. However i am still getting the "ApexType does not have a no-arg constructor" error after enabling this critical update.

I am getting this error when i am passing the wrapper class list from lightning component to apex class.So, I have serialzed the wrapper class in lightning component and deserialized in apex class. Then the issue got fixed.

Anyone else faced the same issue ? Why I am facing this issue with component which are not a part of managed packages/namespace?
Is this a valid fix?

Thanks!
