ImportJSON Google Script trims the first row – Twitter API

The following code is the script I am running in Google Sheets and the second code is the JSON file I am parsing. The problem is that the first row of the JSON file always gets trimmed off. Here is the command I am running in Google sheets:

=ImportJSON("http://www.fantasyfootballnerd.com/service/draft-projections/json/test/QB/", "", "")

Here is the Google Script ImportJSON.gs

  ------------------------------------------------------------------------------------------------------------------------------------
  A library for importing JSON feeds into Google spreadsheets. Functions include:

     ImportJSON            For use by end users to import a JSON feed from a URL 
     ImportJSONViaPost     For use by end users to import a JSON feed from a URL using POST parameters
     ImportJSONAdvanced    For use by script developers to easily extend the functionality of this library

  Future enhancements may include:

   - Support for a real XPath like syntax similar to ImportXML for the query parameter
   - Support for OAuth authenticated APIs (see AddOAuthService__ function for failed experiment)

  Or feel free to write these and add on to the library yourself!
  ------------------------------------------------------------------------------------------------------------------------------------
  Changelog:

  1.2.1  Fixed a bug with how nested arrays are handled. The rowIndex counter wasn't incrementing properly when parsing.
  1.2.0  Added ImportJSONViaPost and support for fetchOptions to ImportJSONAdvanced
  1.1.1  Added a version number using Google Scripts Versioning so other developers can use the library
  1.1    Added support for the noHeaders option
  1.0    Initial release

/**
 * Imports a JSON feed and returns the results to be inserted into a Google Spreadsheet. The JSON feed is flattened to create 
 * a two-dimensional array. The first row contains the headers, with each column header indicating the path to that data in 
 * the JSON feed. The remaining rows contain the data. 
 * 
 * By default, data gets transformed so it looks more like a normal data import. Specifically:
 *
 *   - Data from parent JSON elements gets inherited to their child elements, so rows representing child elements contain the values 
 *      of the rows representing their parent elements.
 *   - Values longer than 256 characters get truncated.
 *   - Headers have slashes converted to spaces, common prefixes removed and the resulting text converted to title case. 
 *
 * To change this behavior, pass in one of these values in the options parameter:
 *
 *    noInherit:     Don't inherit values from parent elements
 *    noTruncate:    Don't truncate values
 *    rawHeaders:    Don't prettify headers
 *    noHeaders:     Don't include headers, only the data
 *    debugLocation: Prepend each value with the row & column it belongs in
 *
 * For example:
 *
 *   =ImportJSON("http://gdata.youtube.com/feeds/api/standardfeeds/most_popular?v=2&alt=json", "/feed/entry/title,/feed/entry/content",
 *               "noInherit,noTruncate,rawHeaders")

 * @param {url}          the URL to a public JSON feed
 * @param {query}        a comma-separated list of paths to import. Any path starting with one of these paths gets imported.
 * @param {parseOptions} a comma-separated list of options that alter processing of the data
 *
 * @return a two-dimensional array containing the data, with the first row containing headers

/**
 * Imports a JSON feed via a POST request and returns the results to be inserted into a Google Spreadsheet. The JSON feed is 
 * flattened to create a two-dimensional array. The first row contains the headers, with each column header indicating the path to 
 * that data in the JSON feed. The remaining rows contain the data.
 *
 * To retrieve the JSON, a POST request is sent to the URL and the payload is passed as the content of the request using the content 
 * type "application/x-www-form-urlencoded". If the fetchOptions define a value for "method", "payload" or "contentType", these 
 * values will take precedent. For example, advanced users can use this to make this function pass XML as the payload using a GET 
 * request and a content type of "application/xml; charset=utf-8". For more information on the available fetch options, see
 * https://developers.google.com/apps-script/reference/url-fetch/url-fetch-app . At this time the "headers" option is not supported.
 * 
 * By default, the returned data gets transformed so it looks more like a normal data import. Specifically:

/**
 * An advanced version of ImportJSON designed to be easily extended by a script. This version cannot be called from within a 
 * spreadsheet.
 * 
 * Imports a JSON feed and returns the results to be inserted into a Google Spreadsheet. The JSON feed is flattened to create 
 * a two-dimensional array. The first row contains the headers, with each column header indicating the path to that data in 
 * the JSON feed. The remaining rows contain the data. 
 *
 * The fetchOptions can be used to change how the JSON feed is retrieved. For instance, the "method" and "payload" options can be 
 * set to pass a POST request with post parameters. For more information on the available parameters, see 
 * https://developers.google.com/apps-script/reference/url-fetch/url-fetch-app .
 *
 * Use the include and transformation functions to determine what to include in the import and how to transform the data after it is
 * imported. 
 *
 * For example:
 *
 *   ImportJSON("http://gdata.youtube.com/feeds/api/standardfeeds/most_popular?v=2&alt=json", 
 *              new Object() { "method" : "post", "payload" : "user=bob&apikey=xxxx" },
 *              "/feed/entry",
 *              "",
 *              function (query, path) { return path.indexOf(query) == 0; },
 *              function (data, row, column) { data[row][column] = data[row][column].toString().substr(0, 100); } )
 *
 * In this example, the import function checks to see if the path to the data being imported starts with the query. The transform 
 * function takes the data and truncates it. For more robust versions of these functions, see the internal code of this library.
 *
 * @param {url}           the URL to a public JSON feed
 * @param {fetchOptions}  an object whose properties are options used to retrieve the JSON feed from the URL
 * @param {query}         the query passed to the include function
 * @param {parseOptions}  a comma-separated list of options that may alter processing of the data
 * @param {includeFunc}   a function with the signature func(query, path, options) that returns true if the data element at the given path
 *                        should be included or false otherwise. 
 * @param {transformFunc} a function with the signature func(data, row, column, options) where data is a 2-dimensional array of the data 
 *                        and row & column are the current row and column being processed. Any return value is ignored. Note that row 0 
 *                        contains the headers for the data, so test for row==0 to process headers only.
 *
 * @return a two-dimensional array containing the data, with the first row containing headers
