Warning: Undefined array key "tab_output" in Drupal\views_bootstrap\Plugin\views\style\ViewsBootstrapAccordion->buildOptionsForm()

The issue have fixed when i checked in bootstrap theme.
But how can fix if not using bootstrap based theme?
I think we can add bootstrap libraries in views template. Any suggestions?

This module is specifically for a Bootstrap theme and is not intended for non-Bootstrap themes. I do not have any suggestions as I do not know what modules may be available for a tabs views style.
