Vector code isn't available???

Problem/Motivation

I installed the dev version but only activated the OpenAI sub module. Then I started seeing these log messages:

Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException: You have requested a non-existent service "plugin.manager.vector_client". Did you mean one of these: "plugin.manager.menu.link", "plugin.manager.condition", "plugin.manager.eca.event", "plugin.manager.eca.action", "plugin.manager.help_section", "plugin.manager.views.argument"? in Drupal\Component\DependencyInjection\Container->get() (line 159 of /var/www/html/t2/web/core/lib/Drupal/Component/DependencyInjection/Container.php).

Even after installing the modules like "Search API Pinecone" and "Search API AI Postgres + PG Vector", the errors continued to appear when I try to go to this URL: /admin/config/openai/search-api-ai-explorer

TIA
