Database is not initialized

Error message

Database is not initialized

What it means

exportDatabase serializes the local SQLite database to a SQL file for backup. It checks AppDataSource.isInitialized first and throws a plain Error if the TypeORM DataSource has not been initialized, since no query runner or tables can be accessed before initialization.

Solutions

1. Await database initialization (AppDataSource.initialize()) before calling exportDatabase/createBackup
2. Check startup logs for the underlying initialization failure and fix it (corrupt/locked DB file)
3. Gate the backup UI/action on an 'db ready' flag
4. Retry the backup after the app reports the database as ready

Example fix

// before
await createBackup();
// after
if (!AppDataSource.isInitialized) await AppDataSource.initialize();
await createBackup();

import { AppDataSource } from './db';
if (!AppDataSource.isInitialized) {
  await AppDataSource.initialize();
}
await createBackup(path);

function isDbReady(ds: { isInitialized: boolean }): boolean {
  return ds.isInitialized === true;
}

try {
  await createBackup(path);
} catch (e) {
  if (e.message === 'Database is not initialized') {
    await waitForDbReady();
    await createBackup(path);
  } else throw e;
}

When it happens

Trigger: createBackup is invoked before the app finished database initialization (e.g. during startup races), or after initialization failed (bad DB file, migration error) so isInitialized stayed false.

Common situations: User triggers backup immediately on app launch before DB init completes; database file locked/corrupt causing init failure; init awaited nowhere before the backup routine runs.
