If I do something simple like:
object[] obj = new object[] { 10, 3 };
var ret = await _nodeServices.InvokeAsync<object>("./NodeScripts/Add.js", obj);

Where Add.js simply adds two numbers together, it works without issue, however if I do this,
object[] obj = new object[] { 10+"", 3+"" };
var ret = await _nodeServices.InvokeAsync<object>("./NodeScripts/Add.js", obj);

It fails complaining about a non-json string, but if I do this, it works properly
object[] obj = new object[] { 10 + "", 3 + "" };
var ret = await _nodeServices.InvokeAsync<string>("./NodeScripts/Add.js", obj);

It works properly. I would assume that using type object would cover anything, but it doesn't appear to work. I'm not sure what's going on, and I don't want to have to figure out types on the fly.
