HI Eleonore, thank you for reaching out about this! I think I can help :

The string that you've used is probably the 'nextPageToken' that was rendered for me at the time of making the article and is no longer valid.

You should be able to find your next page token further down in the json representation of your initial get reponse:

JSON representation

{ "reviews": [ { object (Review) } ],

"averageRating": number,

"totalReviewCount": integer,

"nextPageToken": string

As you can see the top data returned are the reviews followed by average Rating, review counts and then your nextPageToken! you should be able to access the token and then use it with your pageToken query parameter

I hope this helps and merry christmas!

P.s I will clean up the article.
