Here’s what I did: Cloned the repo for the tutorial: https://github.com/sanity-io/tutorial-sanity-blog-react-next

Followed the steps in the readme file. Including deployment to Now.

Currently deployed to: https://testbug.now.sh

I’ve not changed any of the code in the repo, other than following the instructions in the readme. I added some comments to the index page.

I tried including a hardcoded link to the page the dynamic link points to – that works.

Like I said, the blog article page shows 
An unexpected error has occurred.
Refreshing the page renders the page fine.

Have you added https://testbug.now.sh to the CORS settings in manage.sanity.io ?
May 9, 2020, 8:43 AM
Let’s see. I ran: 
sanity cors add <http://localhost:3000> --no-credentials
May 9, 2020, 8:43 AM
But of course I need to add the remote site too…
May 9, 2020, 8:44 AM
Yeah, try that. I think that will fix it
May 9, 2020, 8:44 AM
It does. Thanks very much!
