37 In case google makes changes, here are some snippets used to reverse engineer the format:
39 1. Find which script contains the init data (use the query astolfo+images for this)
40 -----------------------------------------------------------------------------------
42 scripts.find(script => script.search("https://steamcdn-a.akamaihd.net/steamcommunity/public/images/items/622220/f4d2d4074167411a7e15b9a845cf18b434c02af3.jpg") >= 0)
44 2. Reverse engineer format of init data passed to AF_initDataCallback
45 ---------------------------------------------------------------------
47 const findStrings = (obj, path = "") => {
53 let p = path + "." + k
56 found = found.concat(findStrings(v, p))
57 else if (t == "string")
64 console.log(findStrings(initData))
