I got this error when parsing through an API for "tag/#{idnum}/parents"...Normally, you'd expect a response like this:

 {

"parents": [
    {
        "id": 8,
        "tag_type": "MarketTag",
        "name": "internet",
        "display_name": "Internet",
        "angellist_url": "https://angel.co/internet",
        "statistics": {
            "all": {
                "investor_followers": 1400,
                "followers": 5078,
                "startups": 13214
            },
            "direct": {
                "investor_followers": 532,
                "followers": 1832,
                "startups": 495
            }
        }
    }
],
"total": 1,
"per_page": 50,
"page": 1,
"last_page": 1

}

but when I looked up the parents of the market category "adult" (as it were), I got this

{

"parents": [ ],
"total": 0,
"per_page": 50,
"page": 1,
"last_page": 0

}

Now ruby allowed a number of interactions with this thing to occur, but eventually it threw the error about implicit conversion

    parents.each do |p|
        stats = p['statistics']['all']
        selector << stats['investor_followers'].to_i
    end
    selected = selector.index(selector.max)
    parents[selected]['id'] ***<--- CODE FAILED HERE
end
