Error message

database.delete.databaseNotExists

What it means

Thrown by assertDatabaseExists when the named database is not found in the server's metadata listing (Chat2DBContext.getDbMetaData(dbType).databases(connection)). The metadata query succeeds but no returned Database has a name equal to the requested databaseName. This guards against dropping a database that was already removed or never existed.

Solutions

1. Refresh the database list and confirm the database still exists before retrying.
2. Check for exact case sensitivity in the databaseName parameter.
3. If already deleted externally, no action is needed — report success/idempotency to the user.

List<Database> dbs = Chat2DBContext.getDbMetaData(dbType).databases(connection);
boolean exists = dbs != null && dbs.stream().anyMatch(d -> StringUtils.equals(d.getName(), databaseName));
if (!exists) { /* do not call delete */ }

When it happens

Trigger: Calling prepareDatabaseDelete or executeDatabaseDelete with a databaseName that does not match any Database.getName() returned by the dialect's databases() metadata call. Common when the database was dropped by another session between listing and confirmation.

Common situations: Race condition: database deleted by another admin between the UI listing and the user confirming; typo or wrong-case database name; metadata listing filtered or cached and stale.
