-----------------------------------
Summary: camel-pgvector - a vector as a List of Double (as JSON
gives) fails with ClassCastException
Key: CAMEL-26215
URL: https://issues.apache.org/jira/browse/CAMEL-26215
Project: Camel
Issue Type: Bug
Components: camel-ai
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 ClassCastException
A vector given as a List of Double (what a JSON array unmarshals to) fails with
a raw {{ClassCastException}}: {{PgVectorProducer}} (main 2a465aa4814c, lines
151 and 201) reads the body as {{List<Float>}} and {{toFloatArray}} (line 258)
assigns each element to a {{Float}}, for UPSERT and SIMILARITY_SEARCH. Checked
on 4.24.0-SNAPSHOT with the camel-test-infra pgvector container. camel-weaviate
and camel-pinecone have the same problem.
Proposed: convert each element with {{Number.floatValue()}} (and accept
{{float[]}}).
