app_name must not been empty

Error message

app_name must not been empty

What it means

newAddAppReq validates the AddApp JSON body in the tenant Go service; when app_name is an empty string it returns this error, which the SaveApp handler surfaces as a bad-request. It is a plain request-field guard before any persistence.

Solutions

1. Include a non-empty app_name in the request JSON body
2. Fix form validation on the client to require the name field before submit
3. Confirm the JSON key matches the AddAppReq binding tag (e.g. "app_name")

Example fix

// before
{"request_id":"r1","dev_id":3,"cloud_id":"c1"}
// after
{"request_id":"r1","app_name":"myapp","dev_id":3,"cloud_id":"c1"}

if strings.TrimSpace(req.AppName) == "" {
    return errors.New("app_name is required")
}

if err := submitAddApp(req); err != nil {
    if strings.Contains(err.Error(), "app_name must not been empty") {
        return fmt.Errorf("please provide an app name before creating the app: %w", err)
    }
    return err
}

When it happens

Trigger: POST add-app (SaveApp) with JSON body missing the app_name field, containing "", or with the field name cased differently from the binding tag so it binds to empty.

Common situations: Frontend submitting the creation form before the name field is filled; automated scripts building payloads without app_name; struct tag/field renames breaking client payloads after an API change.
