Getting error in React TypeScript: Cannot invoke an object which is possibly ‘undefined’
I am getting this error for Child Component

I’m trying to filter the data by select, but I don’t know why my code doesn’t work. In the console I can see that it correctly shows me the selected items (option). I noticed that the problem is onChange, which shows undefined in the console even though the value is correctly shown.

I have an array of objects that is filled from a json file.

Closed yesterday.

Sorry if i am not explaining well, I am new to typescript programming. I am trying to develop a from for creating and editing order forms. I wanted to reuse the code for the form in other modules, so I tried to make this part a functional component to be loaded by the parent form. I am passing the form data to the child using an interface object as props. I have the same interface object as part of the state of the parent form. I can successfully update the state using a button on the parent form. I can see the props of the child component update to match. The elements of the child component are not updating. It seems the state of the child component isn’t updating when the object is reinitialized. I don’t understand why as I am passing the props using the spread operator.
