Parrot Minidrone Error 1

Hello. I was trying to fly my Parrot Minidrone using my own customized Image Processing and Path Planning subsystems.

It appeared to be working until the interface pop-up window with a big green "START" button appeared on my computer screen.

However, within 0.5 seconds of starting to ascend, the drone shuts down with the error message stating: "Geo-fencing error detected. Shutting down the drone."

I attached the flight log file to this post as well. What I 'suspect' to be most relevant from the log file is the following line: "rsedu_control(): Flight aborted due to error condition 1 !"

Strange; https://uk.mathworks.com/help/simulink/supportpkg/parrot_ug/analyze-flight-log-errors.html does not state anything about the error condition 1...

I would appreciate it if anyone could help me solving this issue.
