# Non-Critical Type Errors - Fix Progress

## Status: In Progress

Fixing non-critical TypeScript type errors systematically.

## ✅ Completed Fixes

### 1. AccountType Enum Issues
- **Files Fixed**:
  - `src/integration/plugins/temenos-adapter.ts`
  - `src/integration/plugins/flexcube-adapter.ts`
  - `src/integration/plugins/iso20022-adapter.ts`
  - `src/integration/plugins/swift-adapter.ts`
- **Fix**: Imported `AccountType` enum and used enum values instead of string literals

### 2. JsonValue Type Issues (Partial)
- **Files Fixed**:
  - `src/core/accounting/reporting-engine.service.ts` - Added `Prisma.InputJsonValue` casting
  - `src/core/admin/dbis-admin/controls/corridor-controls.service.ts` - Added `Prisma.InputJsonValue` casting

## ⚠️ Remaining Issues

Given the large number of errors (hundreds), the remaining errors fall into these categories:

1. **JsonValue Type Mismatches** (~100+ instances)
   - Need to cast `Record<string, unknown>` to `Prisma.InputJsonValue`
   - Pattern: `as Prisma.InputJsonValue`

2. **Property Access Errors** (~50+ instances)
   - Missing properties in Prisma query results
   - Often due to incorrect `include` statements or schema mismatches

3. **Missing Return Statements** (~100+ instances)
   - Route handlers missing explicit returns in all code paths
   - Pattern: Add `return` statements or throw errors

4. **Decimal Method Errors** (~30+ instances)
   - Using `isGreaterThan`, `isLessThan` instead of `greaterThan`, `lessThan`
   - Pattern: Replace method names

5. **Unknown Type Errors** (~20+ instances)
   - Objects typed as `unknown` need type assertions
   - Pattern: Add proper type assertions

## Strategy

Due to the volume of errors, I'm focusing on:
1. **High-impact fixes**: Fixing the most common patterns first
2. **Systematic approach**: Creating patterns that can be applied broadly
3. **Priority files**: Core services and commonly used code paths

## Next Steps

Continue fixing errors systematically, focusing on:
1. JsonValue issues in core services
2. Property access errors that are easy to fix
3. Missing return statements in route handlers
