Error connecting Sanity CMS to a site deployed on Vercel, seeking help with CORS configuration and API endpoint.

Hi all, I've recently started working with the sanity cms, and I'm trying to connect it to a site that I've deployed on vercel. I keep getting the following error
GET <http://localhost:3000//api/experience> net::ERR_CONNECTION_REFUSED
. I've checked all my environment variables as well and made sure that my
.env.local
file has the required keys as follows:
#SANITY_PROJECT_ID=your_project_id
#SANITY_DATASET=your_dataset_name
#SANITY_API_TOKEN=your_sanity_api_token
#SANITY_API_VERSION=2021-03-25 // The API version you want to target 
Has anyone encountered this before? If so I'd really appreciate some help with this. I really don't know where I screwed up. Thanks a lot in advance!

👋 Have you added that port to your CORS origins in sanity.io/manage ?

I added the whole url for the site that vercel generated. Can you share an example of what the correct CORS value is supposed to look like please? 😅

<http://localhost:3000>

Oh, also I just noticed the double
//
before
api
. Is that intended?

So I added localhost:3000 into the cors origin.
Also the // isnt intended. So I used postman to check the vercel url ‘testurl/api/experience’ and it returns data. But for some reason when I check the console of the deployed site, it gives me that error

Would it help if I set a base url value in the env.local file?

user M
there was a typo in some of the url strings that used the baseurl environment variable. Its all good, and the site is deployed too!
