participant User as User/Component
participant Modal as DatabaseModal<br/>🔄 Updated | ●●○ Medium
participant Select as Select Component
participant SetDb as setDatabaseModel<br/>🔄 Updated | ●●○ Medium
participant Reducer as dbReducer
participant State as Database State
User->>Modal: Render DatabaseModal
User->>Select: Select database from dropdown
Select->>SetDb: onChange(database_name)
SetDb->>SetDb: Filter availableDbs for match
Note over SetDb: Added null check:<br/>if (!selectedDbModel) return
SetDb->>Reducer: setDB(DbSelected action)
Reducer->>State: Update database state
State-->>Modal: Re-render with config
```
Critical path: User/Component -> DatabaseModal -> Select Component
-> setDatabaseModel (MODIFIED) -> dbReducer -> Database State
> **Note:** Added null check in setDatabaseModel function to prevent
undefined reference errors when database lookup fails. This defensive guard
returns early if no matching database is found, protecting downstream property
access.
