I have a project and this project is in order to run a contracting and construction company, and I have a file, which is the information for each of the company’s invoices, and this file is a set of fields, but I had this error and I did not know the cause or how can i solve it?
index.js:1 Warning: A component is changing an uncontrolled input to be controlled. This is likely caused by the value changing from undefined to a defined value, which should not happen. Decide between using a controlled or uncontrolled input element for the lifetime of the component. More info: https://reactjs.org/link/controlled-components

>Solution :
If you set as undefined the value prop of your components they become uncontrolled. This is an example:
<TextField
className="mt-8 mb-16"
id="outlined-size-normal"
value={invoice.id} // invoice.id is initially undefined
variant="outlined"
fullWidth
/>
Then, once you run the setInvoice() to define those values the components become controlled.
What you can do to make them always controlled is to set a proper initial value of the state like this:
const [invoice, setInvoice] = useState({ // Note that the initial value is an object and not an array
id: "",
issueDate: null,
netAmount: 0,
taxNumber: 0,
grossAmount: 0
});
Or alternatively you can do this to each of your components:
<TextField
className="mt-8 mb-16"
id="outlined-size-normal"
value={invoice.id || ""}
variant="outlined"
fullWidth
/>
