Error in `fly_mission` example: `Falling back to gimbal protocol v1 (mission_impl.cpp:128)`

[jonazti07]

I'm trying to run the fly_mission example after building in the following way:

cd /path/to/MAVSDK/examples/fly_mission
cmake -Bbuild -H.
cmake --build build -j4

Then, I try to launch:

build/fly_mission udp://:5763

Note that I'm running the SITL of ArduPilot as explained in here and adding the port by typing output add 127.0.0.1:5763 in the terminal.

The error I obtain while trying to run the example is as follows:

[04:09:51|Debug] Falling back to gimbal protocol v1 (mission_impl.cpp:128)
Mission upload failed: Unsupported, exiting.

Interesting, thanks for the issue. I will have to investigate.
