`undefined` Syntax Error in Getting photos not in Album

[micnguyen]

Hi, I'm attempting to retrieve all photos in my Google Photos that isn't in an album. I followed the README.md instructions (get all library items, select all albums to exclude from, add to album called 'No album' (existing)).

However, I get an error below:

17:34:59] SyntaxError: "undefined" is not valid JSON at JSON.parse (<anonymous>) at Api.makeApiRequest (chrome-extension://dhdgffkkebhmkfjojejmpbldmpobfkfo/userscript.html?name=Google-Photos-Toolkit.user.js&id=d0af533b-e45d-49fc-a5b5-045a8ac3fcf3:1294:31) at async Api.getAlbumPage (chrome-extension://dhdgffkkebhmkfjojejmpbldmpobfkfo/userscript.html?name=Google-Photos-Toolkit.user.js&id=d0af533b-e45d-49fc-a5b5-045a8ac3fcf3:1511:26) at async ApiUtils.getAllItems (chrome-extension://dhdgffkkebhmkfjojejmpbldmpobfkfo/userscript.html?name=Google-Photos-Toolkit.user.js&id=d0af533b-e45d-49fc-a5b5-045a8ac3fcf3:2071:22) at async ApiUtils.getAllMediaInAlbum (chrome-extension://dhdgffkkebhmkfjojejmpbldmpobfkfo/userscript.html?name=Google-Photos-Toolkit.user.js&id=d0af533b-e45d-49fc-a5b5-045a8ac3fcf3:2094:14) at async chrome-extension://dhdgffkkebhmkfjojejmpbldmpobfkfo/userscript.html?name=Google-Photos-Toolkit.user.js&id=d0af533b-e45d-49fc-a5b5-045a8ac3fcf3:2768:33

It occurs in the logs here

then it stops finding items and then the script stops. No items are added to the No Album existing album.

Anyone experienced this or know a work around? I don't think it's related to the 20k+ album cap is it, because it hasn't begun adding anything to the new album?

Thanks
