----------------------------------------
Summary: camel-langchain4j-web-search: NullPointerException
unboxing maxResults when a custom WebSearchRequest omits it
Key: CAMEL-24610
URL: https://issues.apache.org/jira/browse/CAMEL-24610
Project: Camel
Issue Type: Bug
Components: camel-langchain4j-web-search
Reporter: Andrea Cosentino
Assignee: Andrea Cosentino
Fix For: 4.23.0
LangChain4jWebSearchProducer.process() passes webSearchRequest.maxResults()
into computeResponse(..., Integer maxResults), which does if (maxResults == 1)
- an auto-unbox of a nullable Integer. In the advanced path, where the user
supplies a custom WebSearchRequest (getConfiguration().getWebSearchRequest() !=
null) that does not set maxResults, langchain4j's WebSearchRequest.maxResults()
is null, so the comparison throws NullPointerException. The default builder
path is safe only because the configuration maxResults defaults to 1.
Fix: null-guard the comparison, e.g. if (maxResults != null && maxResults == 1)
(treating null as the multi-result branch), or default it before comparing.
