DATABASE_NAME_NOT_EMPTY

DATABASE_NAME_NOT_EMPTY

Error message

DATABASE_NAME_NOT_EMPTY

What it means

Thrown by DatabaseService.create when the incoming DatabaseDto has a null, empty, or whitespace-only name. The service requires every new database record to carry a non-blank display name before it validates duplicates or calls the core system. It is a fail-fast input validation guard, not a system fault.

Solutions

1. Set a non-blank name on DatabaseDto before calling create
2. Add a required/not-blank validation on the frontend form for the name field
3. Check the request payload actually contains the 'name' key (correct JSON field naming)
4. If building DTO programmatically, default or reject null names at the call site

Example fix

// before
DatabaseDto dto = new DatabaseDto();
dto.setDescription("analytics");
databaseService.create(dto); // throws DATABASE_NAME_NOT_EMPTY
// after
DatabaseDto dto = new DatabaseDto();
dto.setName("analytics-db");
databaseService.create(dto);

if (dto == null || dto.getName() == null || dto.getName().isBlank()) {
    throw new IllegalArgumentException("Database name is required");
}
databaseService.create(dto);

boolean hasName(DatabaseDto dto) { return dto != null && dto.getName() != null && !dto.getName().trim().isEmpty(); }

try { databaseService.create(dto); } catch (BusinessException e) { if ("DATABASE_NAME_NOT_EMPTY".equals(e.getCode())) { /* prompt for name */ } else { throw e; } }

When it happens

Trigger: Calling POST database-create (DatabaseService.create) with a DatabaseDto whose name field is null, "" or all whitespace.

Common situations: Frontend form submitted without filling the name field; API client omits 'name' in the JSON body; a script sends a DTO built from an optional field that defaulted to null; request deserialization silently drops the name key.
