fix(utils): convert string indices to int in index() function to prevent TypeError

[nordby]

Convert string indices to int in index() function

Closes #4591

Description

This PR modifies the index() utility function to automatically convert string indices (e.g., "0") to integers, preventing TypeError: list indices must be integers or slices, not str errors that occurred when indices were passed as strings.

Changes

def index(iterable, index) -> any:
    if isinstance(index, str) and index.isdigit():  # Safely convert string to int
        index = int(index)
    return iterable[index]
