@maxkatz6
Would following solution be okey to begin with to avoid a crash?

1. Catch NotAllowedError
2. Browser log it, console.error
3. Return an empty array?

it has the disadvantage that it hides errors from developer.

[maxkatz6]

We should throw this exception, so developer can catch and act on it. But it should be consistent with other platforms.
What kind of exception is thrown right now? Can it be handled?
If it's a catch-able and descriptive exception, it works correctly.

[maxkatz6]

It might be appropriate to wrap it in UnauthorizedAccessException (while keeping original JSException as an inner exception).
