Calling await hero.mainFrameEnvironment.document before await hero.goto causes succeeding call to await currFrame.getFrameEnvironment to return null

Code to replicate

import Hero, { IHeroCreateOptions } from "@ulixee/hero"
import { assert } from "node:console";

const TIMEOUT_MS = 100000

async function createHero(): Promise<Hero> {
    const heroOptions: IHeroCreateOptions = {connectionToCore: {host: "localhost:1818"}}
    const hero = new Hero(heroOptions)
    return hero

    const currFrame = hero.mainFrameEnvironment
    const framElem = currFrame.querySelector("[name=frame-top]")
    const frameEnv = await currFrame.getFrameEnvironment(framElem)
    assert (frameEnv !== null, "FrameEnv is null")
}

async function CallMainFrameEnvironmentBeforeGoto() {
    const hero = await createHero()
    await hero.mainFrameEnvironment.document  // This causes the getFrameEnvironment to return `null`
    await GetFrameEnvironment(hero)
    await hero.close()
}
