[Typo]: NOT operator in if-else

[FSBalbuena]

Summary

The code example on server functions with actions has an if checking for an error, but it has a NOT operator.

https://react.dev/reference/rsc/server-functions#server-functions-with-actions

according to the written code, the only returned value for updateName is an error, if there is no name.
Currently the code says "If there is no error, set error state to error" and it does not clean the name input.

"use client";

import {updateName} from './actions';

function UpdateName() {
  const [name, setName] = useState('');
  const [error, setError] = useState(null);

  const [isPending, startTransition] = useTransition();

  const submitAction = async () => {
    startTransition(async () => {
      const {error} = await updateName(name);
      if (!error) { // <---------------------------- we should delete the Not Operator
        setError(error);
      } else {
        setName('');
      }
    })
  }
  
  return (
    <form action={submitAction}>
      <input type="text" name="name" disabled={isPending}/>
      {state.error && <span>Failed: {state.error}</span>}
    </form>
  )
}
