The value of "val" is out of range.

[andrewpuch]

Hello,

I've been seeing some intermittent failures with this error.

The value of "val" is out of range. It must be a safe integer greater than 0. Received 0

Based on the stack trace it's coming from here.

https://github.com/dnlup/doc/blob/next/lib/gc.js#L71

The code I have that should be throwing the error is simplified here.

const doc = require('@dnlup/doc');

const sampler = doc({
  collect: {
    gc: true,
    cpu: false,
    memory: false,
    resourceUsage: false,
    eventLoopDelay: false,
    eventLoopUtilization: false,
    activeHandles: false,
  },
});

sampler.on('sample', () => {
  // Other functionality here
});

Is there something on my end that could be wrong and causing this error to be thrown intermittently? It's not easily reproducible.

Thank you.

Hi @andrewpuch sorry to get back to you so late, what's your version of Node? Maybe there's something that needs better handling in the gc metrics with new versions.

@dnlup I didn't see your notification. I tested the same on Node 18 / 20.
