Incomplete library definition for definition 'vue_router' in extension 'vuejs' upgrading from 8.x-1.x to 3.x

What I can see is, that the config schema is slightly different in 1.x and 3.x but there's no .install files with update hook to update existing configuration:
https://git.drupalcode.org/project/vuejs/-/blob/3.x/config/schema/vuejs....

I think best would be to reset the config to install defaults when upgrading to 3.x.

I found this snippet in the vuejs.install file of 8.x-1.x:

/**
 * Implements hook_update_N().
 */
function vuejs_update_8001(&$sandbox) {
  $module = basename(__FILE__, '.install');
  \Drupal::service('config.installer')->installDefaultConfig('module', $module);
  \Drupal::messenger()->addStatus('Module vuejs Update # 8001 () was executed successfully.');
}

guess wo could do the same, but of course first check, if this needs to be done.

Here we go :) I think this should fix the error and do what's possible.
