fix: add optional chaining

[jacoblogan]

Problem

Codegened code is throwing this error TypeError: undefined is not an object (evaluating 'record.ScanEvents.toArray') when the field is undefined.

Solution

Add optional chaining so that an error won't be thrown and instead the conditional empty array will be returned

Verification

Tests are showing the desired optional chaining.
