This should really be in the newcomers section.
In the future try searching the forum first then if you cannot find the answer then post.
The answer is you have not created camera 1.
Camera 0 is the default camera which does exist.
You are positioning camera 0 but trying to get data for camera 1 which does not exist.
If you do not specify the camera when you "position camera 50,50,50" it is positioning camera 0.
