Exception occurs when calling the value() method using json_pointer

[George-J-Cho]

Exceptions occur in certain situations in the following code lines.

int Range = jsonResult.value(nlohmann::json::json_pointer("/act/cpC/sc/0/parameters/Range"), 65535);

I am a developer of C++ Junior.

As far as I'm debunking
If there is no path value corresponding to the jsonResult, it works fine
It works fine when there is a path value,

Exception occurs when the middle part of the path is transferred to the array.

Is it the intended result? Is it an unknown bug?
I expected that even if part of the path was wrong, it would be the default value of 65535.

If anyone knows, please help me.
Thank you.
