Hello, everyone!
I just deployed my app built on Nest(Node.js Framework)+Next.js to the Vercel.
But after completion of the deployment the app seems to can not be connected to the backend, so the login and registration is shows the error.
I really need in your help!
Please ping me if you're great man in this fields.

Hey there! Your post is a little vague.

Does the error occur locally? Can you elaborate on the error further? Can you provide URLs to the deployment, or the project ID? Does the project fail to deploy or is the error observed as part of a web request? What is the backend? What is the error?

Thanks!

But it was working on local perfectly with all functionalities!
The curious thing was that It was not working with the command "yarn start:next", it should be "yarn start:dev" to be fully activated with the backend in my local.
But how can the Vercel launch the app with "yarn start:dev"?

Sounds like you should reconsider your scripts to better suit what's happening! Here is how you can alter your install command.

Thank you!
Can you suggest this in details for me?
I don't get it watching your link.

If you're unfamiliar with your own code base, I'd suggest starting from scratch and understanding the principles, before jumping in with both feet 😉. To update the Install command, this is achieved in your project's UI.
