I haven't tested it out in terms of running the model, but I just looked at the code. Minor comments, but looks good to me 👍 Thanks for fixing! 🚀

Looks overall good, thanks for digging so deep, that must not have been fun... 💯 ⭐

I cannot get this to run though, so before merging, let's please check together why I cannot get this to work with Google - might be an issue on my side, but I just want to be sure.
