1. Added Err() method to CollectedResult (pkg/neo4j/neo4j.go:68-72):
- The resultiter.Neo4jResultIterator interface requires Err() error
- CollectedResult was missing this method, causing the type assertion to fail
- Since CollectedResult pre-fetches all records, Err() always returns nil
2. Fixed nil pointer dereference in buildCypherQuery (pkg/neo4j/query-events.go:173):
- Changed if *f.Limit > 0 to if f.Limit != nil && *f.Limit > 0
- This prevents a panic when filters don't specify a limit
3. Simplified parseEventsFromResult signature (pkg/neo4j/query-events.go:185):
- Changed from func (n *N) parseEventsFromResult(result any) to accept *CollectedResult directly
- This eliminates the runtime type assertion since ExecuteRead already returns *CollectedResult
- Removed the now-unused resultiter import
Replaced individual environment variable access with a unified `DatabaseConfig` struct for all database backends. This centralizes configuration management, reduces redundant code, and ensures all options are documented in `app/config/config.go`. Backward compatibility is maintained with default values and retained constructors.
