"Your request could not be completed' error when transferring to Google Photos on iPhone 12

FWIW during the last two weeks (the old style) Google Photos takeout has had an issue where albums could not be selected. But today it works again.

So you might try your somewhat unrelated workflow again.

Each time I try to "Copy your photos and videos to Google Photos" and after authenticating with Google and clicking on Continue, I get the following: "Your request could not be completed. This action could not be completed because of an error. Try again later." No actual error is shown with this message.

How do I get past this error?

By contacting google support or looking at their help site.

I'm initiating the transfer through apple's https://privacy.apple.com/ site. I would imagine Apple would have the error that I would need to troubleshoot. Would you still recommend Google's support?

Yes.
