Answer 1

I don't see any state that use setTasks on your screenshot (please provide some code and not a picture btw), but it's probably because you want to add an object to a state that you initialize with a string. So replacing a string by an object is a non-trivial action that may crash your app elsewhere.

In order to avoid that, just declare a type for your object, and specify the type of the state with it.

 // type object type Task = { id: string; title: string; description: string } // state const [tasks, setTasks] = useState<Task[]>([])
