Fix Error in measure not throwing (#1956)

## Description

`measure` checks if the `x` values is exactly `-1234567.0` - if it is, it's an error. if it isn't, a result is available.

We returned an incorrect vector from the native `measure` function.

## Changes


- Updated native method `measure` to correctly return error-ish values
