decide endpoint is throwing Error 500s on Page Load

We are getting an Error 500 - Internal Server Error on Page Loads from a MixPanel /decide/ endpoint which uses "versions=1". Can someone explain what this decide endpoint does and if there's an issue with this endpoint throwing an Error 500?

This is the code snippet from MixPanels script that is initiating this call ->

c.J(document, "change", b, D, p); c.J(document, "click", b, D, p) }, Bb: {}, aa: function (a) {

                if (!document || !document.body) {

                    console.log("document not ready yet, trying again in 500 milliseconds...");

                    var b = this; setTimeout(function () { b.aa(a) }, 500)

                } else {

                    var d = a.c("token"); if (-1 < this.Gb.indexOf(d)) console.log('autotrack already initialized for token "' + d + '"'); else if (this.Gb.push(d), !this.ed(a)) {

                        var e = c.bind(function (b) { if (b && b.config && b.config.enable_collect_everything === p) { if (b.custom_properties) this.Bb = b.custom_properties; a.p("$web_event", c.extend({ $title: document.title }, this.Eb("pageview"))); this.Lc(a) } else a.__autotrack_enabled = D }, this); a.i(a.c("api_host") + "/decide/", {

                            verbose: p, version: "1",

                            lib: "web", token: d

                        }, a.ja(e))

                    }

                }

            }

Our current implementation uses the following ->

Script: https://cdn.mxpnl.com/libs/mixpanel-2-latest.min.js

• mixpanel.init("accountKey");
• mixpanel.identify("uniqueUserId");
• mixpanel.track("Page View", {"Environment" : "Test"});

On Page Load, 4 API calls are made to the MixPanel endpoints ->
