A NEQTO device enters safe mode to protect the device in a variety of situations, such as insufficient memory, errors during reboot, etc. The most common cause of safe mode booting is insufficient memory, so this answer will address how to confirm and resolve this cause on the NEQTO Console.
We recommend identifying the problem-causing area of your script. On the NEQTO Console, causes of safe mode booting are viewable at [node] → [Recent Events] (It will be displayed right before "Engine error Entering Safemode..."). Please review the script to see if deeply nested callbacks, arrays with a large number of elements, etc. are the cause of the problem.
・Detecting Safe Mode on the Console
By registering "Entering safe mode" as an event, users can receive notifications when their devices enter safe mode. Please view the NEQTO documentation for more detail. In the case of low memory, the event type should be "Engine." By specifying an event level, messages related to safe mode can be selectively acquired.
