>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #3558571. --> Reported by: [jbuttler](https://www.drupal.org/user/3437983) >>> <p>Whenever I try to uninstall the deprecated AI Search, I receive an error Plugin (milvus) instance class "Drupal\ai_vdb_provider_milvus\Plugin\VdbProvider\MilvusProvider" does not exist.</p> <p>I have reinstalled and configured Milvus 1.1.0-beta2 but this still does not allow me to uninstall AI Search.</p> <p>1. Uninstall AI search with drush. The response is:<br> "The following extensions will be uninstalled: ai_search, ai_vdb_provider_milvus".<br> 2. I confirm the uninstall.<br> 3. Milvus module is uninstalled.<br> 4. An error in the CLI is generated:<br> "In Container.php line 159: You have requested a non-existent service "milvus_v2.api".<br> 5. This error prevents the AI search module from being uninstalled.<br> 6. Attempt to uninstall AI Search again using drush. The response is:<br> "In DefaultFactory.php line 97: Plugin (milvus) instance class "Drupal\ai_vdb_provider_milvus\Plugin\VdbProvider\MilvusProvider" does not exist.<br> 7. I resinstall Milvus and try again. Go back to step 1. This prevents AI search from ever being uninstalled.</p> <p>I have followed the procedures at <a href="https://www.drupal.org/project/ai_vdb_provider_milvus/issues/3485610">https://www.drupal.org/project/ai_vdb_provider_milvus/issues/3485610</a> and installed the patch successfully, but this still does not allow uninstallation of the AI search module.</p> <p>Any help is greatly appreciated. Thank you for your time!</p>
