IPInfo now makes a request to ipoid's api for some of its data. If the ipoid api response has data in unexpected formats, IPInfo will throw an exception such as:

Error: exception of type TypeError: Argument 1 passed to MediaWiki\\IPInfo\\Info\\IPoidInfo::__construct() must be of the type array or null, string given, called in /var/www/html/w/extensions/IPInfo/src/InfoRetriever/IPoidInfoRetriever.php on line 87
