Index exceeds the number of array elements. Index must not exceed 2.

This error message typically occurs when trying to access an element in an array using an index that is greater than the number of elements in the array. In this case, the index must not exceed 2, meaning that the array has either 1, 2, or 3 elements.

To resolve this error, you should check the size of the array and ensure that the index you are using to access it is within the bounds of the array. You can also use conditional statements to check the size of the array before accessing it to avoid this error.
