node-cron - Deprecation warning: imediateStart is deprecated and will be removed

Question

I updated nodejs from 8 to 10.12 and receive that warning message.

D:\BitBucket\EA Studio>node index
DEPRECIATION: imediateStart is deprecated and will be removed soon in favor of the options param.
...

package.json

{
  "dependencies": {
    ...
    "node-cron": "^2.0.3",
}

Usage:

"use strict";

const cron = require("node-cron");
cron.schedule("5 * * * *", () => null, false);

Any solutions?

Since I don't use imediateStart in my code, the warning origin must be within the internal code of the node-cron. Do the developers made that to not forget to update their own code? how much better would be to show: "This version of node-cron uses deprecated code. Please update it to version xxx as soon as it is released".

Google? First result: https://github.com/node-cron/node-cron/issues/100 — robertklep, Nov 12 '18 at 13:29
Yes, you are right. the warning comes from node-cron. I'll edit my question. — Miroslav Popov, Nov 14 '18 at 06:59

Just replace

cron.schedule("5 * * * *", () => null, false);

with

cron.schedule("5 * * * *", () => null, {scheduled:false});

From node-cron documentation on schedule method:

options Object: Optional configuration for job scheduling.

Options

scheduled: A boolean to set if the created task is schaduled. Default true;

timezone: The timezone that is used for job scheduling;

Run the script with --trace-warnings flag. eg.: node --trace-warnings index.js. It will give you a detailed info what causes the warning.

Thank you. Unfortunately nothing useful. I have the same deprecation warning message. – Miroslav Popov Nov 14 '18 at 06:51
