I am getting an error during the page load I think true code but console declare warning forEach() is not a function Help me please if you have time. Thank you for the help.

function duty() {
  let tasks;

  if (localStorage.getItem("tasks") === null) {
    tasks = [];
  } else {
    tasks = JSON.parse(localStorage.getItem("tasks"));
  }

  tasks.forEach(function (item) {
    const li = document.createElement("li");

    li.className = "collection-item";

    li.appendChild(document.createTextNode(item));

    const link = document.createElement("a");

    link.className = "delete-item secondary-content";
    link.innerHTML = "<i class='fas fa-trash'></i>";

    li.appendChild(link);

    taskList.appendChild(li);
  });
}
