Error message

USER_APP_NAME_REPEAT

What it means

USER_APP_NAME_REPEAT is thrown by createApp when appMstService.exist() finds an existing app with the same app name for the user. App names must be unique, so duplicate-name creation is rejected before the tenant service is called.

Solutions

Choose a different, unique app name and retry.
Check existing apps first (list apps / appMstService.exist) and reuse the existing app instead of creating a new one.
If the name was left over from a failed previous creation, delete the stale app then recreate.
Make automated naming unique (suffix with timestamp/UUID).

Example fix

// before
publishApiService.createApp(new CreateAppVo("my-app", "desc")); // may throw if name taken
// after
String name = "my-app";
if (appMstService.exist(name)) {
    name = name + "-" + System.currentTimeMillis();
}
publishApiService.createApp(new CreateAppVo(name, "desc"));

Defensive patterns

Strategy: validation

Validate before calling

if (appMstService.exist(appName)) { throw new BusinessException(ResponseEnum.USER_APP_NAME_REPEAT); }

Try / catch

try { publishApiService.createApp(vo); }
catch (BusinessException e) { if (e.getCode() == ResponseEnum.USER_APP_NAME_REPEAT) { showNameTakenMessage(); } else throw e; }

Prevention

Check name availability asynchronously as the user types.
Use unique suffixes in automated/CI app creation.
Reuse existing apps instead of recreating with the same name.

When it happens

Trigger: Calling the create-app API with an appName that already exists in app_mst; retrying a create that actually succeeded earlier (client didn't see the response).

Common situations: User re-submits a form after a timeout; automation scripts create apps in a loop without unique names; copy-pasting an existing app's name.
