… with apiFetch for improved error handling
Pull Request Review: Bugfix/jdbc UIThis PR addresses hostname resolution issues for the UI when running on a different machine than the API, and adds ARM64 Linux build support. Overall, this is a well-structured improvement with good error handling and documentation. Strengths1. Excellent API Configuration Abstraction
2. Superior Error Handling
3. Consistent Refactoring Critical Issues1. GitHub Actions YAML Syntax Error (BLOCKER) Multi-line scripts need pipe operator. Current code will fail CI/CD. Should be: - name: Rename deb with version

if [ -f "datacaterer_*.deb" ]; then
mv datacaterer_*.deb datacaterer_VERSION_amd64.deb2. Potential JSON Parsing Error JSON.parse may fail if options.body is already an object. Add type checking or try-catch. 3. Timeout Configuration Inconsistency Error message references window.DATA_CATERER_TIMEOUT but code doesn't support it. 4. Build Matrix Confusion linux-amd64 job has unused matrix strategy. Should be removed. SecurityNo critical security issues found. Minor suggestion: sanitize URLs in error messages to prevent credential leakage. TestingMissing test coverage for new JavaScript module.

Bug: GitHub Actions matrix.arch reference in non-matrix job
The linux-amd64 job references ${{ matrix.arch }} for the Java architecture, but this job no longer uses a matrix strategy (it was split from the original linux job which had a matrix). This will result in an empty or undefined architecture value, causing the Java setup step to fail or use incorrect architecture settings.
- Introduced configurable CORS settings via environment variables, allowing for stricter security controls. - Updated PlanRoutes to log CORS configuration at startup for better visibility. - Refactored connection testing service to utilize a shared SparkSession, improving performance and resource management. - Fixed foreign key property name handling to align with backend expectations, ensuring proper loading of foreign key links in the UI.

Bug: Toast message displays "null" for undefined details
The toast messages display ${result.message} ${result.details} but result.details is an Option[String] on the backend, which serializes to null when empty. This causes toast messages to display text like "Connection successful null" when details aren't provided. The code should handle the case where details is null or undefined, perhaps using result.details || '' or a conditional.

- Added Cache-Control headers to responses for static UI resources, setting a max-age of 1 day and requiring revalidation. - Updated routes in PlanRoutes to include cache control for HTML and SVG resources, improving performance and resource management.
- Updated error handling in saveCredentials and executePlan functions to throw errors instead of rejecting promises, enhancing error propagation and debugging capabilities. - This change ensures that errors are properly caught and logged, improving overall reliability of the UI components.
PR Review: Bugfix/jdbc UIOverall AssessmentThis is a substantial and well-implemented PR that adds critical UI features, improves CI/CD processes, and enhances the developer experience. The changes are well-tested with both Scala integration tests and JavaScript unit tests. However, there are some security considerations and minor improvements to consider. Strengths1.

5. CORS Configuration
Security ConcernsCritical: Connection Testing May Log Sensitive Credentials Location: ConnectionTestService.scala:32 While the specific log line is safe, the Connection object contains passwords and credentials. Ensure that:
Recommendation: Add explicit password masking in error handling and verify all error paths sanitize sensitive data. Medium: Connection Test Service Uses DriverManager Location: ConnectionTestService.scala:101 Direct use of DriverManager.getConnection is acceptable for testing. Current implementation is correct with proper resource cleanup in finally block. Consider adding connection timeout properties for production hardening. Potential Issues1. Application.conf Cleanup Deleted 112 lines of connection configurations from application.conf. This appears to be a breaking change. Questions:
Recommendation: Ensure changelog documents this breaking change and migration path. 2. Missing Input Validation No evidence of rate limiting or input validation on POST /connection/test endpoints. Recommendations:
3. Toast History Persistence Review if error messages in toast history contain sensitive information (connection strings, stack traces with internal paths). Code Quality Improvements1. Magic Numbers
2. Error Handling in CI/CD Location: docker-action.sh:30 Commented-out exit 1 means build continues even if Maven publish fails. Either uncomment to fail fast or document why this is intentionally non-fatal. Performance Considerations1. Shared SparkSession for Connection Testing Excellent design: Reusing SparkSession avoids expensive initialization overhead. Ensure SparkSessionManager properly handles concurrent connection tests and temporary configurations do not leak between tests. 2. Cache Control Headers Good: 1-day cache with revalidation is reasonable for static UI assets. Consider shorter max-age for development builds. Documentation1.

Issues: 🔴 Critical: Connection Repository Test Has Wrong Source ExpectationsIn ConnectionRepositoryTest.scala:119-137, the tests verify that saved connections have source=file, but I noticed the Connection model defaults to source=file in its constructor (models.scala:124). However, connections loaded from application.conf should have source=config. The test doesn't verify the actual loading mechanism from config files. Consider adding a test that:

Bug: showLoginBox crashes when login elements are missing
The login.js file initializes usernameInput and tokenInput from DOM elements at module load time, but index.html no longer contains the login-related elements (login-box, username, token inputs). When showLoginBox() is called from shared.js on plan failure with "User not found" or "Invalid user credentials" errors, it attempts to call .focus() and .select() on null values, causing a runtime error. The login UI was removed but the code path that triggers it remains.
Note
Adds UI connection testing with robust API config and toasts, enables CORS and JDBC config mapping in backend, prevents deleting config-based connections, refactors UI data handling, and upgrades CI to versioned multi-arch builds with arm64 packages.
