I have this code snippet:

    const historicalDataTable = await findElementByClass(
      "table",
      elementClass,
      page
    ); // This is a custom function I wrote. Works as expected.


    const tableBody = await historicalDataTable.$eval(
      "tbody",
      (el) => el.children.length
    );

    console.log(tableBody);

This works as expected and returns the correct amount of children. However when I do

 const tableBody = await historicalDataTable.$eval(
      "tbody",
      (el) => el.children
    );

And remove the length, it returns undefined. What is going on here?
