Drupal AI Assistant API Plugin Error: 'Plugin does not exist'

Created on 24 April 2025, 19 days ago

Problem/Motivation

When installing all necessary modules to build a chatbot, creating the chatbot assistant, placing the chatbot block, and attempting to use it, a persistent error appears in the logs. This error prevents the chatbot from functioning correctly.

The issue is not reproducible. It should be some local installation issue.

Steps followed:

Used ollama provider as ai assistant

Enabled the ai deepchat bot block in content region

In homepage tried using the ai deepchatbot

No error poped up.

This seems a duplicate of 🐛 Error everytime I use the chatbot "plugin does not exist" Active .

There seems to be a typo in the quoted error message: Drupal\ai_assistant_api\AiAssistantActionPluginManag"r is clearly not a correct class name, nor is Drupal\ai_as"istant_api\AiAssistantActionPluginManager shown in the other issue.
