I created custom node that i inserted on button click. Button was added to toolbar. There is the code of node that I inserted

  @action insertCheckList() {
    const currentNode = this.getSelectionNode();
    const currentLi = currentNode.parentElement.closest('li');
    const editorContent = document.querySelector('.note-editable');

    if (currentLi) {
      const currentCheckList = currentLi.closest('.note-check-list');

      if (!currentCheckList) {
        return;
      }

      const items = currentCheckList.querySelectorAll('li');
      if (items.length === 1) {
        editorContent.removeChild(currentCheckList);
        (editorContent as HTMLInputElement).focus();
        setTimeout(() => this.moveCaret(0), 100);
      }
      return;
    }

    const container = document.createElement('ul');
    container.classList.add('note-check-list');
    container.innerHTML = '<li><span class="note-icon-check">' +
      '<span class="note-check-list-text"></span>' +
      '</span></li>';
    this.context.invoke('editor.restoreRange');
    this.context.invoke('editor.focus');
    this.context.invoke('editor.insertNode', container);
    this.moveCaret(0, '.note-check-list-text');

    const currentChecklist = (this.getSelectionNode() as HTMLElement).closest('.note-check-list');

    if (currentChecklist && currentChecklist.previousElementSibling && currentChecklist.previousElementSibling.textContent === '') {
      editorContent.removeChild(currentChecklist.previousElementSibling);
    }

    if (currentChecklist && currentChecklist.nextElementSibling && currentChecklist.nextElementSibling.textContent === '') {
      editorContent.removeChild(currentChecklist.nextElementSibling);
    }
  }

The error is throw after that I add custom node, select text of lines before and after node, and the node itself. After selecting I change selected nodes to ordered or unordered list and this error thows. How can I fix this?
