Im trying to run a script from my .net core 2.1 application. Here is the line how i call it:
var foo = await _nodeServices.InvokeAsync<string>("./Scripts/jsService");

And here's my simple test javascript:

module.exports = function (callback) {
    callback("foobar");
};

But all i get is an exception:
Microsoft.AspNetCore.NodeServices.HostingModels.NodeInvocationException: 'foobar'

I can see my returned string in the exception but why is it giving me this exception when everything seems to be working?
