-------------------------------------
Summary: camel-langchain4j-chat: NPE if only producer is used
Key: CAMEL-20863
URL: https://issues.apache.org/jira/browse/CAMEL-20863
Project: Camel
Issue Type: Bug
Components: camel-ai
Affects Versions: 4.7.0
Reporter: Jiri Ondrusek
Assignee: Jiri Ondrusek
If endpoint uses only a producer (example from camel-quarkus [integration
tests|https://github.com/apache/camel-quarkus/blob/main/integration-tests/langchain4j-chat/src/main/java/org/apache/camel/quarkus/component/langchain/chat/it/OllamaRoute.java])
Producer for multiple messages requires
_CamelToolExecutorCache.getInstance().getTools()_ to return something (!=
null) see
[code|https://github.com/apache/camel/blob/main/components/camel-ai/camel-langchain4j-chat/src/main/java/org/apache/camel/component/langchain4j/chat/LangChain4jChatProducer.java#L142C53-L142C101]
I checked that only place which is adding something to the cache is a
[consumer|https://github.com/apache/camel/blob/main/components/camel-ai/camel-langchain4j-chat/src/main/java/org/apache/camel/component/langchain4j/chat/LangChain4jChatEndpoint.java#L104],
which does not seem to be correct.
