…inting and type safety improvements
This commit finalizes the read-model rebuild implementation with comprehensive
code quality improvements, type safety enhancements, and bug fixes across the
backend and data-processing services.
CHANGES (Backend):
- app.module.ts: Registered ReadModelRebuildModule
- read-model-rebuild/: Various improvements:
* Rebuild controller: Replaced hardcoded role strings with UserRole enum
* Rebuild service: Added proper type safety with isAxiosError guard,
improved error handling with getErrorDetails(), and fixed lock service
method calls (tryAcquire/release)
* Rebuild scheduler: Improved error handling with proper type guards
* DTOs: Removed unused imports, fixed formatting, added proper type safety
* Entity: Added IsNull() for contract_id queries
* Migration: Formatted enum arrays for better readability
- Various files: Fixed union type formatting (horizon-client, webhook, portfolio,
soroban-event guards, latency-budget health)
CHANGES (Data Processing):
- requirements.txt: Added python-jose[cryptography] for JWT support,
pinned httpx version for stability
- account_operation_ingestor.py:
* Replaced non-existent RateLimitExceededError with status code check (429)
* Removed unused imports and variables
* Fixed cursor reset logic
- kpi_computer.py:
* Improved exception handling with specific InvalidOperation
* Removed unused imports
* Fixed operation detection logic
- rebuild_routes.py: Removed unused datetime import
- models.py: Removed duplicate KPI constants (already defined elsewhere)
- logger.py: Added Union type for level parameter, improved type safety
- tests: Fixed test account address length, added proper setUp with context
managers for dependency patching
CODE QUALITY IMPROVEMENTS:
- ESLint compliance: Union types formatted correctly, consistent spacing
- Type safety: Added proper type guards for error handling
- Import optimization: Removed unused imports across all files
- Error handling: Standardized error extraction with getErrorDetails()
- Null safety: Used IsNull() for nullable query conditions
BUG FIXES:
- Fixed non-existent RateLimitExceededError import in account_operation_ingestor
- Fixed lock service method calls (tryAcquire/release instead of acquireLock/releaseLock)
- Fixed test account address length validation
- Fixed KPI constants duplication in models.py

… setup This commit fixes test compatibility for Python 3.9 by replacing the self.enterContext() pattern (Python 3.11+) with the traditional patch().start()/addCleanup(patcher.stop) pattern. CHANGES: - test_account_operation_ingestor.py: Replaced self.enterContext() calls with patcher.start() and self.addCleanup(patcher.stop) for Python 3.9 compatibility IMPACT: - Tests now run successfully in CI environments using Python 3.9 - No functional changes to test coverage or assertions Related: CI compatibility, Python version support
