ExtendScript: Determine wether a camera layer is "One-Node Camera" or "Two-Node Camera"

[avi23837866f7yk]

No documentation found of how to make that determination using ExtendScript.

In order to work around that I'm currently using the following hack:

const isTwoNodeCamera = camera.pointOfInterest.canSetExpression;

Is there a better and safer way?

I recently looked into this and couldn't find a way to specify the type of camera.

I'm not sure if your way is particularly unsafe, as `canSetExpression` returns a boolean value. 

Alternatively, maybe you can use a try/catch to simply see if you can access the pointOfInterest property? If not, you can move on to the rest of your code.
