Unable to deploy hosting

[Biggest-Bee]

[REQUIRED] Environment info

firebase-tools: 11

Platform: Windows

[REQUIRED] Test case

[REQUIRED] Steps to reproduce: Steps to Reproduce Firebase Next.js Executable Detection Bug:

Environment Setup
Windows operating system
Node.js installed
Firebase CLI installed globally
Next.js project with React 18.x and Next.js 15.0.0
Project Configuration
package.json with:
json
"next": "15.0.0",
"react": "^18.2.0",
"react-dom": "^18.2.0"
firebase.json with:
json
"hosting": {
"source": ".",
"frameworksBackend": {
"region": "us-central1"
}
}
Install Dependencies
bash
npm install --legacy-peer-deps
Attempt Firebase Deployment
bash
firebase deploy
Expected Result: Firebase should detect Next.js and deploy successfully

Actual Result:

Error: Could not find the next executable.
Key Factors:

Windows environment (symlink/executable detection issues)
Firebase CLI Next.js framework integration (early preview)
Next.js 15.0.0 within Firebase's supported range (12-15.0)
Executable exists at node_modules/next/dist/bin/next but Firebase cannot locate it
Workarounds Attempted:

Manual creation of node_modules/.bin/next.cmd
Global Next.js installation
PowerShell execution policy changes
Firebase CLI upgrades
All failed to resolve the detection issue
This appears to be a Firebase CLI bug specific to Windows Next.js framework integration executable detection.

[REQUIRED] Expected behavior: It deploys to my website

[REQUIRED] Actual behavior: It ran into an error and doesnt deploy

Hey @Biggest-Bee, thanks for reaching out. I'm currently unable to reproduce the error. I tried deploying on both macOS and Windows machines, but both deployments work. Could you share the output of running:

• firebase --version - firebase-tools v11 is a pretty old version and it might be worth updating to recent versions.
• node --version - so we can check if the issue occurs on a specific version of node

Also, could you share a minimal reproducible example with us? This will help us accurately reproduce the issue.
