Cannot read property 'whenEmitted' of undefined

[josh-hemphill]

I'm trying to use the library in a vue.js project, and it seems that it keeps track of it's state in the Global this, which I think is what is creating this error somehow. If I break on the error, it shows this:

/**
     * Saves the provided function as a handler for the connection
     * success Whenable event
     * 
     * @param {Function} handler to be issued upon connection
     */
    DynamicPlugin.prototype.whenConnected = 
           Plugin.prototype.whenConnected = function(handler) {
        this._connect.whenEmitted(handler);
    }

Where this is the global this and has no property _connect.

Here is the trace

TypeError: Cannot read property 'whenEmitted' of undefined
    at DynamicPlugin.whenConnected.Plugin.whenConnected (jailed.js?c164:787)
    at eval (utils.js?a2b6:70)

    at asyncGeneratorStep (asyncToGenerator.js?1da1:3)
    at _next (asyncToGenerator.js?1da1:25)

This is how I'm using it:

    const plugin = new jailed.DynamicPlugin(forCompile);
    plugin.whenFailed(x => console.log(x));
    await promisify(plugin.whenConnected);
    const result = await promisify(plugin.remote.evaluateAll);
    console.log(result);
    return { rows: result, evaluate: plugin.remote.evaluate };
