Default is false. <br>***Note:*** Enabling this setting will result in dropped telemetry whenever an internal error occurs. This can be useful for quickly identifying issues with your configuration or usage of the SDK. If you do not want to lose telemetry while debugging, consider using `consoleLoggingLevel` or `telemetryLoggingLevel` instead of `enableDebug`. |
