| Events do not appear | Initialize with logLevel: LogLevel.debug, verify the API key and appIdentifier, and confirm init() ran before any logEvent() call. |
init() called more than once | Subsequent calls are ignored. Call destroy() then init() again to change configuration. |
| Events not sent immediately | Expected — delivery follows batchSize / flushIntervalSeconds. Call flush() to force immediate delivery. |
| Properties are dropped | Check that values are one of the supported types (String, num, bool, DateTime, null, Map, List). |
