Recursive Method Error Analysis

Which of the following statements best describes the error in the faultySearch method and its consequence?

public class RecursionError {
    public static int faultySearch(int[] arr, int index, int key) {
        if(index >= arr.length) return -1;
        if(arr[index] == key) return index;
        return faultySearch(arr, index, key);
    }
    
    public static void main(String[] args) {
        int[] array = {1, 2, 3};
        System.out.println(faultySearch(array, 0, 2));
    }
}
