Jon 6057d1d7fd 🔧 Fix authentication and document upload issues
## What was done:
 Fixed Firebase Admin initialization to use default credentials for Firebase Functions
 Updated frontend to use correct Firebase Functions URL (was using Cloud Run URL)
 Added comprehensive debugging to authentication middleware
 Added debugging to file upload middleware and CORS handling
 Added debug buttons to frontend for troubleshooting authentication
 Enhanced error handling and logging throughout the stack

## Current issues:
 Document upload still returns 400 Bad Request despite authentication working
 GET requests work fine (200 OK) but POST upload requests fail
 Frontend authentication is working correctly (valid JWT tokens)
 Backend authentication middleware is working (rejects invalid tokens)
 CORS is configured correctly and allowing requests

## Root cause analysis:
- Authentication is NOT the issue (tokens are valid, GET requests work)
- The problem appears to be in the file upload handling or multer configuration
- Request reaches the server but fails during upload processing
- Need to identify exactly where in the upload pipeline the failure occurs

## TODO next steps:
1. 🔍 Check Firebase Functions logs after next upload attempt to see debugging output
2. 🔍 Verify if request reaches upload middleware (look for '�� Upload middleware called' logs)
3. 🔍 Check if file validation is triggered (look for '🔍 File filter called' logs)
4. 🔍 Identify specific error in upload pipeline (multer, file processing, etc.)
5. 🔍 Test with smaller file or different file type to isolate issue
6. 🔍 Check if issue is with Firebase Functions file size limits or timeout
7. 🔍 Verify multer configuration and file handling in Firebase Functions environment

## Technical details:
- Frontend: https://cim-summarizer.web.app
- Backend: https://us-central1-cim-summarizer.cloudfunctions.net/api
- Authentication: Firebase Auth with JWT tokens (working correctly)
- File upload: Multer with memory storage for immediate GCS upload
- Debug buttons available in production frontend for troubleshooting

Implementation Plan

  • 1. Audit and analyze current codebase configuration issues

    • Identify all environment files and their conflicts
    • Document current local dependencies (storage and database)
    • Analyze upload error patterns from logs
    • Map current deployment artifacts and scripts
    • Requirements: 1.1, 1.2, 1.3, 1.4
  • 2. Remove redundant and conflicting configuration files

    • Delete duplicate .env files (.env.backup, .env.backup.hybrid, .env.development, .env.document-ai-template)
    • Consolidate environment variables into single .env.example and production configs
    • Remove local PostgreSQL configuration references from env.ts
    • Update config validation schema to require only cloud services
    • Requirements: 1.1, 4.1, 4.2
  • 3. Implement Google Cloud Storage service integration

    • Create / confirm GCS-only file storage service replacing current local storage
    • Implement GCS bucket operations (upload, download, delete, list)
    • Add proper error handling and retry logic for GCS operations
    • Configure GCS authentication using service account
    • Requirements: 2.1, 2.2, 4.3
  • 4. Migrate existing files from local storage to GCS

    • Create migration script to upload all files from backend/uploads to GCS
    • Update database file_path references to use GCS URLs instead of local paths
    • Verify file integrity after migration
    • Create backup of local files before cleanup
    • Requirements: 2.1, 2.2
  • 5. Update file storage service to use GCS exclusively

    • Replace fileStorageService.ts to use only Google Cloud Storage
    • Remove all local file system operations (fs.readFileSync, fs.writeFileSync, etc.)
    • Update upload middleware to work with GCS temporary URLs
    • Remove local upload directory creation and management
    • Requirements: 2.1, 2.2, 2.3
  • 6. Fix document upload route UUID validation errors

    • Analyze and fix invalid UUID errors in document routes
    • Add proper UUID validation middleware for document ID parameters
    • Improve error messages for invalid document ID requests
    • Add request correlation IDs for better error tracking
    • Requirements: 2.2, 3.1, 3.2, 3.3
  • 7. Remove all local storage dependencies and cleanup

    • Delete backend/uploads directory and all local file references
    • Remove local storage configuration from env.ts and related files
    • Update upload middleware to remove local file system operations
    • Remove cleanup functions for local files
    • Requirements: 2.1, 2.4
  • 8. Standardize deployment configurations for cloud-only architecture

    • Update Firebase deployment configurations for both frontend and backend
    • Remove any local deployment scripts and references
    • Standardize Cloud Run deployment configuration
    • Update package.json scripts to remove local development dependencies
    • Requirements: 1.1, 1.4, 4.1
  • 9. Enhance error logging and monitoring for upload pipeline

    • Add structured logging with correlation IDs throughout upload process
    • Implement better error categorization and reporting
    • Add monitoring for upload success/failure rates
    • Create error dashboards for upload pipeline debugging
    • Requirements: 3.1, 3.2, 3.3
  • 10. Update frontend to handle GCS-based file operations

    • Update DocumentUpload component to work with GCS URLs
    • Modify file progress monitoring to work with cloud storage
    • Update error handling for GCS-specific errors
    • Test upload functionality with new GCS backend
    • Requirements: 2.1, 2.2, 3.4
  • 11. Create comprehensive tests for cloud-only architecture

    • Write unit tests for GCS file storage service
    • Create integration tests for complete upload pipeline
    • Add tests for error scenarios and recovery
    • Test deployment configurations in staging environment
    • Requirements: 1.4, 2.1, 2.2, 2.3
  • 12. Validate and test complete system functionality

    • Perform end-to-end testing of document upload and processing
    • Validate all environment configurations work correctly
    • Test error handling and user feedback mechanisms
    • Verify no local dependencies remain in the system
    • Requirements: 1.1, 1.2, 1.4, 2.1, 2.2, 2.3, 2.4
