I am working on a c++ native module within electron that formerly used v8 methods to register methods. I have been converting this code to use N-API calls. Here is a snippet of code from this module:

static napi_value initialise(napi_env env, napi_value exports)

 napi_status rcd;
 napi_value fn;

 try
 
 rcd = napi_create_function(env, 0, 0, do_about, 0, &fn);
 if(rcd != napi_ok)
 throw std::invalid_argument("unable to create about");
 rcd = napi_set_named_property(env, exports, "about", fn);
 if(rcd != napi_ok)
 throw std::invalid_argument("unable to register about");
 
 catch(std::exception &e)
 napi_throw_error(env, 0, e.what()); 
 return exports;
 // initialise

NAPI_MODULE(NODE_GYP_MODULE_NAME, initialise)

When I try to load this within the electron main process, I am getting an access violation in the expansion of the NAPI_MODULE macro. I have attempted to debug this by having visual studio attach to the three electron processes before require statement for my native module. I have verified that the initialise() function is not being called but there is an access violation.

Is this something that others have encountered?

  Maybe sharing the access violation stack trace would be helpful.
