I don't know how to specify the token for method Photos() ?

[janvda]

Most likely my implementation is not correct:

An extract of the relevant part of my code:

const Photos = require('googlephotos');
...
node.photos = new Photos(node.config.credentials.accessToken);
... 
async function get_albums_list(node){
                node.warn("get_albums_list ...")
                let response = await node.photos.albums.list();
                node.warn("get_albums_list response :"+ response);
                alert(response);
            }

get_albums_list(node);

FYI node.config.credentials.accessToken is "ya29.Il-zB8z2qrcP7qP3YVpUlt8NCsvb1ZxtsIHTlPi71HN30wFLJs7c5q...".

when running the above code I am getting error

This is more of a question for googleapis. Heres a link to their code examples: https://github.com/googleapis/google-api-nodejs-client/blob/master/samples/sheets/quickstart.js

An example of how I used it with googlephotos api: https://github.com/mcpengelly/instagram-saved-to-google-photos-album/blob/master/oauth.ts

Also, I've adapted their code here. but i suggest using their example because this code is incomplete:

app.get('/oauth2callback', (req, res) => {
  const code = req.query.code;
  client.getToken(code, (err, tokens) => {
    ...
    client.credentials = tokens;
    doSomethingWithToken(client);
    ...
  })
})

function doSomethingWithToken(client) {
    new Photos(client.credentials.access_token)
    ...
}

Thanks for the very fast response.

Based on your input, I further looked into it. My code was correct but the access token (string) that I passed to new Photos() was apparently no longer valid.

I have created new credentials and generated new tokes using these credentials and that resolved the issue.
