Почему я получаю ошибку Assignment to constant variable, хотя переменная была создана через let

import {activeNotesData} from "../../data/activeNotesData.js";

function findParentId(el) {
    return el.parentNode.id
}

function deleteNote(id) {
    activeNotesData = activeNotesData.filter(note => note.id !== id)
}

export const createInteractionPanel = (itemId) => {

    let interactionPanel = document.createElement("div");
    interactionPanel.setAttribute("id", itemId)


    let deleteIcon = document.createElement("img");
    deleteIcon.src = "images/garbageIcon.svg";
    deleteIcon.className = "note-interaction-icon";

    deleteIcon.addEventListener('click', function () {
        deleteNote(findParentId(this))
    });

    interactionPanel.appendChild(deleteIcon);

    return interactionPanel;
}

export let activeNotesData = [
    {
        id: 123,
