Webpart list property using PNPJS

So I made the following changes. I added the catch method and put another return in there but the IDE still doesn't think that my code always returns as a value.

  protected fetchLists(): Array<IPropertyPaneDropdownOption> {
    let options: Array<IPropertyPaneDropdownOption> = new Array<IPropertyPaneDropdownOption>();
    sp.web.lists.select('ID', 'Title', 'DefaultViewUrl').orderBy('Title').get().then(function(data) {
      for (let i = 0; i < data.length; i++) {
        if ((data[i].DefaultViewUrl.includes('/Lists/')) && 
        (
          (data[i].Title != 'SharePointHomeCacheList') || 
          (data[i].Title != 'TaxonomyHiddenList')
        )) {
          options.push({
            key: data[i].Title,
            text: data[i].Title,
          });
        }
      }
      return options;
    }).catch(function(e) {
      return options;
    });
  }
