This error appeared in the console for me when using the Flag module with clientside_validation installed:

VM3499:21 Uncaught TypeError: Cannot read property 'messages' of undefined
at :21:24
at :71:3
........

At the time I was editing a node and clicking on the button to report a flag.

This does not cause an actual problem unless javascript files are aggregated.

If javascript files are aggregated then this error prevents to open the modal dialog form from appearing.

The error happens when the library `cv.jquery.validate` is added by BigPipe and compressed.
I just disabled the library compressing in hook_library_info_alter as:


/**
 * Implements hook_library_info_alter().
 */
function clv_coupons_commerce_library_info_alter(&$libraries, $extension) {
  // During JS compressing the library is added
  // by BigPipe with errors, hence disable the compressing.
  // @see https://www.drupal.org/project/clientside_validation/issues/3211333
  if (isset($libraries['cv.jquery.validate']['js']['js/cv.jquery.validate.js'])) {
    $libraries['cv.jquery.validate']['js']['js/cv.jquery.validate.js']['preprocess'] = FALSE;
  }
}

now it works.

Patch #234 for issue 1988968 helped me with this issue. the errors in the console were also preventing CKeditor in a layout builder popup module from rendering. I'm running drupal 9.2.7

We were having this problem. It was preventing CKEditor from loading in Layout Builder blocks. We added the hook implementation in #4 to one of our modules and that fixed it for us.

The problem also went away if we disabled clientside_validation_jquery.

Just wanted to inform that when you suddenly got this error on May 2024.
It was caused by this https://community.cloudflare.com/t/jsdelivr-expired-certificate-may-2024...

jsdelivr SSL Expired, should be changed into other cdn.
the config should be located in /admin/config/user-interface/clientside-validation-jquery-settings
