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.

The value() function will throw an exception if you provide it with a json pointer that doesn't exist.

@gregmarr I don't have a specific plan. I am honestly a bit afraid to have this one shot at a new major version, because it feels like a lot of pressure to get this right.

[gregmarr]

I was mostly looking for "here's a list of things that we want to fix in a new major version". Maybe just a v4.0 tag would work for now.

[nlohmann]

Yes, I can do that.

@gregmarr I created a label "V4 candidate" that can be used as a quick bookmark for these issues. But we should have a proper roadmap as well.

@nlohmann
If there is a problem with the path, will it be improved to be specified as the default value? (In the v4 version)
I'm sorry for the awkward expression because I'm not good at English.
Thank you so much for your answer.
