System Memory Info closes App

[Thomy13]

Hi,

My app immediately closes when trying to do the following:

import { memory } from "system";
console.log("memory "+memory.js.used+"/"+memory.js.total);

It's a copy of the example given here: https://dev.fitbit.com/build/reference/device-api/system/

My console output:

[11:00:38 AM]Sideload successful!
[10:18:34 AM]Loaded and evaluated: file:///android_asset/bootstrap.js
[11:00:41 AM]App Started

Is the JS memory function deprecated?

The API is still valid.

The timestamps on those log entries look weird though.

How long does the app run for before it terminates?
