NoSuchSessionError: invalid session id , selenium test for looping WebElements

Question

Trying to loop through the selector for multiple elements and getting invalid session after the first element.

await container.findElements(By.css('.sfsdff')).then((elements) => {
    if (elements.length !== 0) {
      elements.forEach((data) => {
        data.getText().then((data1) => {
          console.log(data1);
        }, err => console.error(`error: ${err}`));
      });
    } 
  });

elements has exact count that the selector meant to get from the page, its just the loop that the next elements are unable to process after first.

Thanks
