What happended?

After a successful deployment on Vercel, I'm getting a 500 error.

Expected behavior

This project is running smoothly on my Ubuntu server.

Actual behavior

In the logs of Vercel, I see this error:
SyntaxError: Unexpected token 'D', "Direct IP "... is not valid JSON

Hey @Datsunco, can't view your repository. But i don't believe this is an issue with Medusa. Anything you changed in there? Ensure that you're not running on edge.

[Datsunco]

I'm so sorry, I just now opened my repository.

Hey @Datsunco, once again, I don't believe this is a Medusa error. I can see that after your first commit, the entire dep tree has been removed and installed based on your runtime.

Can you create a new project and deploy that on vercel? I just tried it and works ok

Hi, I have the same issue. I changed nothing. I believe it is a Medusa error

[bxclib2]

Hi, I know where the issue is.

If you log the error
you will get Error body: Direct IP access is not allowed in Vercel's Edge environment (hostname: *****)

Vercel Edge runtime won't allow http request to a ip address. Just attach a domain name to your store backend will solve the issue.
