Incident Response: Root Cause Analysis
Issue Summary
The deployment is failing with the error message: "Build Failed: The specified Root Directory 'srt-app' does not exist. Please update your Project Settings."
Investigation
Based on the error message and screenshot provided, I can identify that this is a configuration issue with your Vercel deployment. The system is looking for a directory named "srt-app" as the root directory for your Next.js project, but this directory doesn't exist in your repository.
Sequence of Events
Root Cause Analysis
The root cause of this issue is a mismatch between the configured root directory in your Vercel project settings and the actual structure of your repository.
There are several possible scenarios that could have led to this:
- Typo in Configuration: The most likely cause is a typo in your Vercel project settings. The configuration specifies "srt-app" but the actual directory might be "src-app" or simply "src".
- Directory Structure Change: Your project structure may have changed, and the "srt-app" directory was renamed or moved, but the Vercel configuration wasn't updated.
- Repository Structure Mismatch: If you recently changed your repository structure or migrated from another repository, the new repository might not have the same directory structure.
- Monorepo Configuration: If your project is part of a monorepo, the root directory setting might be pointing to the wrong location.
Recommended Solutions
Update Project Settings:
- Go to your Vercel project dashboard
- Navigate to "Settings" > "General"
- Find the "Root Directory" setting
- Update it to the correct directory (likely "src" if you're using the src directory pattern in Next.js 1)
- If your Next.js app is at the root of your repository, leave this field empty
Verify Repository Structure:
- Check your repository to confirm the correct directory structure
Common Next.js directory structures include:
- Root-level app/pages directories
- src/app or src/pages directories 1
Check for typos:
- Verify if there's a typo in the directory name ("srt-app" vs "src-app")
- Ensure case sensitivity matches (e.g., "SRC-app" vs "src-app")
Add a vercel.json file (if needed):
- If you need special configuration, consider adding a vercel.json file to your repository:
{ "buildCommand": "npm run build", "outputDirectory": ".next", "rootDirectory": "correct-directory-name" }
Preventative Measures
- Implement CI/CD Checks: Add pre-deployment checks that verify your project structure matches your deployment configuration.
- Documentation: Document your project structure and deployment configuration for team reference.
- Version Control for Configuration: Keep your Vercel configuration in version control when possible (using vercel.json).
- Review Process: Implement a review process for deployment configuration changes.
Conclusion
This issue is a configuration mismatch between your Vercel project settings and your actual repository structure. The simplest fix is to update the Root Directory setting in your Vercel project to match your actual repository structure. If your Next.js application is at the root of your repository, you should leave the Root Directory field empty.
