NOT DONE - failing deployment on vercel

### What is the problem?

Hello,

i am trying to deploy an app to vercel but the deployment always fails. The reason seems to be an injected `target` property that vercel is somehow not supporting. **Building locally works fine, just the deployment fails**

To make this work, I tried to use some other node version and installed node 13.x up to 16.x. I also tried to downgrade blitz to blitz 2.x which did not work. I tried different node versions from node 20.x up to 24.x, nothing resolved the deployment error.

I also started a new blitz app from scratch using `blitz new`and tried to deploy it to vercel as well. But here, the same error occured.

A different answer suggested to fix it with upgrading next to 15.x. This did not resolve the issue for me. The same error persisted.

### Paste all your error logs here:

### What are detailed steps to reproduce this?

1. Clone a new blitz app with `blitz new ...`
2. Try to deploy it to vercel without any changes

### Run `blitz -v` and paste the output here:

```
Blitz version: 3.0.2 (global)
Blitz version: 3.0.2 (local)
macOS | darwin-arm64 | Node: v24.2.0

Package manager: npm

System:
OS: macOS 15.3.2
CPU: (12) arm64 Apple M3 Pro
Memory: 170.56 MB / 36.00 GB
Shell: 5.9 - /bin/zsh
Binaries:
Node: 24.2.0 - /opt/homebrew/bin/node
Yarn: 1.22.21 - /opt/homebrew/bin/yarn
npm: 11.6.4 - /opt/homebrew/bin/npm
npmPackages:
@blitzjs/auth: 3.0.2 => 3.0.2
@blitzjs/next: 3.0.2 => 3.0.2
@blitzjs/rpc: 3.0.2 => 3.0.2
@prisma/client: 5.4.2 => 5.4.2
blitz: 3.0.2 => 3.0.2
next: 13.5.4 => 13.5.4
prisma: 5.4.2 => 5.4.2
react: 18.2.0 => 18.2.0
react-dom: 18.2.0 => 18.2.0
typescript: 5.9.3 => 5.9.3

```

And this is my next.config.js

```
// @ts-check
const { withBlitz } = require("@blitzjs/next")

/**
* @type {import('@blitzjs/next').BlitzConfig}
**/
module.exports = withBlitz({})
```
