>          Components: camel-langchain4j-embeddings
>    Affects Versions: 4.21.0
>            Reporter: Federico Mariani
>            Assignee: Omar Atie
>            Priority: Major
>             Fix For: 4.22.0

>         Attachments: LangChain4jEmbeddingStoreMissingEmbeddingHeaderTest.java

> The ADD action in {{LangChain4jEmbeddingStoreProducer.add()}} (lines 129-148) does not validate that the {{CamelLangChain4jEmbeddingsEmbedding}} header is present. When the header is missing, the producer calls {{EmbeddingStore.add(null)}} — the store receives a null embedding and the exchange completes without any error, unlike the missing-action case which is properly rejected with {{NoSuchHeaderException}}.
> Depending on the store implementation this either throws a store-specific NPE later or silently persists garbage.
> Attached reproducer {{LangChain4jEmbeddingStoreMissingEmbeddingHeaderTest}} uses a recording stub store: it receives {{add(null)}} and the exchange carries no exception.
> *Fix*: fail fast with a meaningful validation error when the embedding header is absent (same pattern as the action validation).
> _This issue was drafted by Claude Code on behalf of Federico Mariani._
