----------------------------------------
Summary: camel-langchain4j-agent: validate that an agent was
resolved before use
Key: CAMEL-24614
URL: https://issues.apache.org/jira/browse/CAMEL-24614
Project: Camel
Issue Type: Bug
Components: camel-langchain4j-agent
Reporter: Andrea Cosentino
Assignee: Andrea Cosentino
Fix For: 4.23.0
LangChain4jAgentProducer resolves the agent from the registry with
lookupByNameAndType(agentId, Agent.class), which returns null when no matching
bean exists. With no agent/agentConfiguration/agentFactory configured and no
registry bean named agentId, this.agent stays null and process() throws an
opaque NullPointerException at agent.chat(...) instead of a clear configuration
error. Fix: after the resolution chain in doInit, throw a clear
IllegalArgumentException when agent == null && agentFactory == null.
_Reported by an automated functional audit._
