V8 - All fields are undefined [closed]

1

I use V8 and I create an object like this :

_template->SetInternalFieldCount(1);

v8::NamedPropertyHandlerConfiguration *handler = new v8::NamedPropertyHandlerConfiguration;

handler->getter = &BSONObject::getter;

handler->setter = &BSONObject::setter;

_template->SetHandler(*handler);

Local<Object> obj = _template->NewInstance();

When I use my getter I put the variable in the JS object like this :

info.GetReturnValue().Set(prop->ToString());

All my fields are undefined but I print prop->ToString() on the line just above and it print the good value.

I don't know why is it undefined...

c++ undefined v8

This question appears to be off-topic. The users who voted to close gave this specific reason:

• "Questions seeking debugging help ("why isn't this code working?") must include the desired behavior, a specific problem or error and the shortest code necessary to reproduce it in the question itself. Questions without a clear problem statement are not useful to other readers. See: How to create a Minimal, Complete, and Verifiable example." – VTT, Toby Speight, Oussema Aroua, Matthieu Brucher, Killzone Kid

There are several examples of using SetHandler in various ways in https://chromium.googlesource.com/v8/v8/+/master/test/cctest/test-api-interceptors.cc.
