Thanks for your PR.
I do think the default value of 30000ms is already set in the interface (index.js).

See the following code:

createCpuProfile(cpuProfilePath, duration) {
    if (duration === undefined) {
      duration = 30000;
    } else {
      duration = parseInt(duration);
    }
    return this._impl.createCpuProfile(cpuProfilePath, duration);
  }

That doesn't work for you?

Missed that. Thanks for pointing it
