Webdriverio throws undefined element for row in a table

Question

I have to click on a button located in the first row of a table after navigating from another page. After I go to my page I check that the rows in the table are not undefined by using waitUntil.

    waitUntil(
      () => {
        return (          
           myPage.myList.myRows != undefined
        );
      },
      Timeouts.SixtySeconds,
      'Rows were not found',
    );

however if I try to do anything on the row by using myPage.myList.myRows[0] I get an undefined error for myRows[0]. I have checked again and again the locators and everything seems to be fine. I am at a loss about what to do.
