Get accounts locations reviews return not found

I tried to retrieve google reviews like this :

 do
  try{
    dump($locationName);
    if (!empty($this->googleReviews))
       $listReviewsResponse = $this->googleReviews->listAccountsLocationsReviews($locationName, array('pageSize' => 50,
                                    'pageToken' => $listReviewsResponse->nextPageToken));
       $reviewsList = $listReviewsResponse->getReviews();
    foreach ($reviewsList as $index => $review) {
  ...
  while($listReviewsResponse->nextPageToken)

But this call listAccountsLocationsReviews return

{
  "error": {\n
  "code": 404,\n
  "message": "Requested entity was not found.",\n
  "errors": [\n
    {\n
      "message": "Requested entity was not found.",\n
      "domain": "global",\n
      "reason": "notFound"\n
    }\n
  ],\n
"status": "NOT_FOUND"\n
}\n
}

Have you an idea about this problem ? Thank you in advance
