…ad of raising `ValueError` (#7435)

* Refactor string_to_dict to return None if there is no match instead of raising ValueError

instead of having the pattern of using try-except to handle when there is no match, we can instead check if the return value is None; we can also assert that the return value should not be None if we know that should be true
