Uncaught ReferenceError: once is not defined

hi, I think the issue is resolved already. Please share screenshot so can help.

Hi there! Seems like your problem is caused by code changes being implemented with Drupal 10 compatibility update.

In Drupal 10 we don't have a core/jquery.once library and are using core/once which was introduced in Drupal 9.2. You can read about it in documentation here → .

If you want to use this module, you should upgrade your site's core version to 9.2^ or downgrade the module's version to 2.0.2 or prior to that.

Hi @paulrad, you are absolutely right.

• Thanks for reporting and following up on the issue.
• Closing as won't fix.
• Better to update to latest Drupal ~9.5.0 version or upgrade to Drupal ~10.1.0
