Native add-on compilation error in NODE_MODULE function on 12.0.0, works on 11.15.0 - node.js

Question

I'm maintaining the aerospike package, a client SDK for the Aerospike No-SQL database. On Node.js versions up to and including v11.15.0 this package compiles and works fine. But starting with v12.0.0 I'm getting a compile time error when building the native add-on, that I haven't been able to resolve.
The error occurs in this function (slightly abbreviated):
void Aerospike(Handle<Object> exports, Handle<Object> module)
{
AerospikeClient::Init();
export("client", Nan::New<FunctionTemplate>(client)->GetFunction());
// more exports
}
NODE_MODULE(aerospike, Aerospike)
And the error I'm getting is:

The module uses the older C++ add-on API, not n-api. I'm using the latest version nan v2.13.2.
The error can also be seen in this Travis CI job: https://travis-ci.org/aerospike/aerospike-client-nodejs/jobs/523788617.

The correct signature for the second arg of NODE_MODULE is void InitializerFunction(Local<Object> exports[, Local<Value> module]) (ref). Handle was removed from v8; it's replacement is Local.
If you're not upgrading to N-API, NAN is a good way to avoid these changes.
