Error `contains` undefined in Google Maps JS API

Question

function gB(a,b,c){b[rb](function(b){var e="Om"==c?b[gl]():b.get("latLngPosition");e&&!b.pegmanMarker&&a[Vb](e)?rp(c,"-v",b):sp(c,"-v",b)})};

It tells me there's an error here.

• Firefox calls it "a is undefined".
• Chrome calls it "Uncaught TypeError: Cannot call method 'contains' of undefined"
• Safari calls it "TypeError: 'undefined' is not an object (evaluating 'a[gb]')"

This is related to markers. After walking through breakpoints:

• The "b" variable is some marker data with title, map, position, etc attributes.
• The "gl" variable is "getPosition".
• The "e" variable ends up evaluating out to a position object (lat/lng).
• The "a" variable is being passed in as undefined, which explains the error.
• The "Vb" variable is "contains", which explains the Chrome error.

Since this is a Google script, I'm wondering if I have something funky going on in my codebase or how to resolve this. Anyone else run into this? What is "a" supposed to be?

This is being called from this in main.js.

ig[E].forEach = function(a) {
    var b = this.va, c;
    for (c in b)
        a[Gc](this, b[c])
};

In this code, "a" references the snippet block shown above. So a[Gc](this, b[c]) essentially evaluates to gB.call(this, markerObject);

This was because I had been using "3.exp" which is the experimental API. I guess there was an error happening in it and I didn't realize. Switched to production, 3.13, and it fixed the bug. Cheers to geocodezip for asking about the API version.
