The expression $errors of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.

            throw new \InvalidArgumentException(sprintf(
                "Invalid set of coordinates: values at offsets [%s] could not be converted to numbers",
