-----------------------------------

             Summary: camel-weaviate - a vector as a List of Double (as JSON 
gives) fails with ArrayStoreException
                 Key: CAMEL-26214
                 URL: https://issues.apache.org/jira/browse/CAMEL-26214
             Project: Camel
          Issue Type: Bug
          Components: camel-weaviate
            Reporter: Claus Ibsen
             Fix For: 4.24.0


Found while adding the catalog body types of weaviate, pinecone and pgvector 
(CAMEL-24961, PR #28402).

h4. 1. A List of Double vector fails with ArrayStoreException

A vector given as a List of Double (what a JSON array unmarshals to) fails with 
a raw {{ArrayStoreException}}: {{WeaviateVectorDbProducer}} (main 2a465aa4814c, 
lines 132, 154 and 200) does {{(Float[]) elements.toArray(new Float[0])}} for 
CREATE, UPDATE_BY_ID and QUERY. Checked on 4.24.0-SNAPSHOT with the 
camel-test-infra weaviate container. camel-pinecone and camel-pgvector have the 
same problem.

Proposed: convert each element with {{Number.floatValue()}}.
