puppeteer Error Unknown key: " " when trying to press space key

I was trying to make a fun project by automating a typing test using puppeteer, but when I want to press space this error pops up

D:\scraping\puppeteer tut\node_modules\puppeteer\lib\cjs\puppeteer\common\assert.js:28
        throw new Error(message);
              ^

Error: Unknown key: " "

    at D:\scraping\puppeteer tut\typingTest.js:37:34
    at processTicksAndRejections (node:internal/process/task_queues:96:5)

The code for the project is

const puppeteer = require("puppeteer");

(async () => {
  const browser = await puppeteer.launch({
    headless: false,
    defaultViewport: false
  });
  const page = await browser.newPage();
  await page.goto("https://www.speedtypingonline.com/typing-test", {
    waitUntil: "load"
  });
  const word = await page.evaluate(() => {
    let lineDivArr = document.querySelectorAll(".blockLines");
    let charArr = [];
    let ActualChar = [];
    lineDivArr.forEach((line) => {
      charArr.push(line.querySelectorAll('span'));
    })

    charArr.forEach((char) => {
      char.forEach((c) => {
        ActualChar.push(c.outerText);
      })
    })
    return ActualChar;
  })
  for (const element of word) {
    if (element == String.fromCharCode(32)) {
      await page.keyboard.press(String.fromCharCode(32));
    } else await page.keyboard.press(element);
  }
})();

In addition to the above error, I occasionally encounter this error mentioned here:

Error: We either navigate top level or have old version of the navigated frame

Kindly help me resolve the issue.
