Uncaught Google\Exception: (search) unknown parameter: 'pageToken'

[FelixSche]

Following the google documentation is a parameter you can send in to get the next page of articles. https://developers.google.com/shopping-content/reference/rest/v2.1/reports/search?apix_params=%7B%22merchantId%22%3A283548%2C%22resource%22%3A%7B%22pageToken%22%3A%22COgH%22%2C%22query%22%3A%22SELECT%20product_view.id%2C%20product_view.title%2C%20product_view.brand%2C%20product_view.price_micros%2C%20product_view.currency_code%2C%20price_competitiveness.country_code%2C%20price_competitiveness.benchmark_price_micros%2C%20%20price_competitiveness.benchmark_price_currency_code%20FROM%20PriceCompetitivenessProductView%22%7D%7D

Environment details

• OS: Mac OS Ventura 13.1
• PHP version: 8.2.3
• Package name and version: google/apiclient: 2.15
• google/apiclient-services: ShoppingContent

Steps to reproduce

1. Request a report from the google content for shopping api
2. grab the nextpagetoken from the response and query the content API for shopping again this time including the pageToken in the request body

Code example

$oSearchRequest = new Google_Service_ShoppingContent_SearchRequest();
  $query = 'SELECT product_view.id, product_view.title, product_view.brand, product_view.price_micros, product_view.currency_code, price_competitiveness.country_code, price_competitiveness.benchmark_price_micros,  price_competitiveness.benchmark_price_currency_code FROM PriceCompetitivenessProductView';
  $oSearchRequest->setQuery($query);

  $oShopping = new Google\Service\ShoppingContent($oGoogle);
  if ($sPageToken != '') {
    $optParams = ['pageToken' => $sPageToken];
    $oReport = $oShopping->reports->search($iMerchantID, $oSearchRequest, $optParams);
  } else {
    $oReport = $oShopping->reports->search($iMerchantID, $oSearchRequest);
  }

Without the pageToken the request is working just fine. The API also returns a next pageToken. The error only occurs when trying to send the request including the token.

Okay I just found out that pageToken is part of the searchbody and not of the optParameters. My bad. Maybe add this to the docs though. That was rather hard to figure out.
