Some methods of DJICamera always return -1006 error (Get parameter failed) after drone reconnect

[YaroTs]

Drone: Mavic 2 Zoom Mobile SDK: 4.14

I call this methods of DJICamera object:

1. open func getHybridZoomSpec(completion: @escaping (DJICameraHybridZoomSpec, Error?) -> Void)
2. open func getHybridZoomFocalLength(completion: @escaping (UInt, Error?) -> Void)

and -1006 error always gets back.

at the same time e.g. open func getModeWithCompletion(_ completion: @escaping (DJICameraMode, Error?) -> Void) works normally

Steps to reproduce:

1. Connect remote controller
2. Turn remote controller and drone on
3. Turn drone off
4. Turn drone on
5. Try to call an above methods of DJICamera object
6. Notice -1006 error is returned

I'm kind of disappointed by this answer. I expect sdk to be ready to make calls after "connected" notification arrives.

Could you, please, consider sending this type of notifications when there is a confidence that product components are ready to answer? Or, at least, adding another kind of notifications like "ready"?
