Steps to reproduce at high level:

1. Create a a device template with 2 Telemetry values (temp,humidity), 1 command, 1 Writeble Property (bool)
2. Create a device
3. Follow steps in sample ESP 8286 and connect using necessary 5 parameters (wifi and IOT central device parameters)
4. Telemetry values are reported fine
5. If a Property is updated from IOT Central UI for the device, crash in ESP 8286 firmware while processing updated event payload
   Crash logs look something like this:
   =================

• Entering event handler of eventName: SettingsUpdated
• • [SettingsUpdated] event was received. Payload => {"LatestFWV":{"value":11},"$version":19}
• ERROR: echoDesired has failed due to payload doesn't include the property: twin
  =================
• To be specific, crash observed at following code block:

void jsobject_free(jsobject_t *object) { if (object->tokens != NULL) { IOTC_FREE(object->tokens); object->tokens = NULL; } }
