No output "success": false

I am trying to detect a currency with Esp32-Cam. For this i follow the tutorial of EDGE IMPLUSE YouTube video which show how to detect something with Esp32-Cam.
First of take some picture and trained the as follows.

Then download the library and include it in my Arduino IDE. After that i use example code of your github by changing this

// Modify the following line according to your project name
// Do not forget to import the library using "Sketch">"Include Library">"Add .ZIP Library..."
#include <esp32Cam10taaka_inferencing.h>

I have this error in serial monitor

What’s going wrong?
