Vercel and Next.js Error - Session Does Not Match Project Host

16 replies
Last updated: May 18, 2021
Hey Sanity family, we are currently in a bit of a weird spot where we are receiving an error on our production server (Vercel) but not locally. I've searched around looking for information on the error message/code and have found nothing. I'm hoping that the Sanity Team can help shed some light on this. Here's the error:
body: {
  errorCode: 'SIO-401-AWH',
  message: 'Session does not match project host',
  statusCode: 401,
  error: 'Unauthorized'
},
This is occurring only when we're using the Preview client. Again, everything works perfectly locally. Screenshots in thread
👉
The web client is running on
Nextjs and we're hosting on Vercel for what it's worth.

If you open the Functions tab in Vercel then hit this page again, does it offer any insight?
May 18, 2021, 5:47 PM
Yes, do you want me to post the full error?
May 18, 2021, 5:48 PM
Sure.

Anything else I can provide?
May 18, 2021, 6:08 PM
Have you tried generating a new token to ensure Vercel has the right one?
May 18, 2021, 6:11 PM
Yes, we did that with no luck.
May 18, 2021, 6:12 PM
Wait. We just did it again and it might have worked...
May 18, 2021, 6:14 PM
Standby...
May 18, 2021, 6:14 PM
It works now 🙃
May 18, 2021, 6:16 PM
I think it was a space at the end of the token.
May 18, 2021, 6:16 PM
Thanks for the help 🙏 🎉
May 18, 2021, 6:17 PM
Awesome!
May 18, 2021, 6:17 PM
You’re welcome!
