Describe the Bug

One of the paths on my site is /dev, like this: example.org/dev. When I try to deploy to Vercel using the @astrojs/vercel package, the following error is reported.

The build step keeps getting stuck on this error and doesn't stop.

If you delete the /dev path, or rename it to /dev1, it will not report an error and the site will deploy properly.

If you run npm run build locally or on stackblitz, no errors will be reported.

What's the expected result?

The site should be deployed successfully, and the following is the successful log output.

This problem also occurs on Linux (WSL) and also reports errors for paths like /etc.

I found a temporary workaround, probably a bug in the package @vercel/nft.

1. Patch the package with pnpm patch @vercel/nft.
2. Open the temp package dir in the terminal.
3. Find /out/node-file-trace.js and add the following line of code at line 310.
4. Run the pnpm patch-commit <temp-package-dir> prompted in the terminal before to apply the patch.

        const { deps, imports, assets, isESM } = analyzeResult;
        if (isESM) {
            this.esmFileList.add((0, path_1.relative)(this.base, path));
        }
        await Promise.all([
            ...[...assets].map(async (asset) => {
                // patch
+               if (asset.startsWith('/dev')) return;
                
                const ext = (0, path_1.extname)(asset);
                if (ext === '.js' || ext === '.mjs' || ext === '.node' || ext === '' ||
                    this.ts && (ext === '.ts' || ext === '.tsx') && asset.startsWith(this.base) && asset.slice(this.base.length).indexOf(path_1.sep + 'node_modules' + path_1.sep) === -1)
                    await this.emitDependency(asset, path);
                else
                    await this.emitFile(asset, 'asset', path);
            }),
            ...[...deps].map(async (dep) => this.maybeEmitDep(dep, path, !isESM)),
            ...[...imports].map(async (dep) => this.maybeEmitDep(dep, path, false)),
        ]);
