@sdetweil I’ve added ‘debug: true,’ inside the config block but I don’t seem to get any other errors regarding the MMM-GooglePhotos module (or any other errors at all in fact) apart from this one below. This is after restarting MM using pm2:

pm2 restart mm && pm2 logs --lines=100

I’ve also tried it without limiting the lines and I just get this same 429 error over and over.

Thanks so much for the help by the way!
