Claus Ibsen resolved CAMEL-25746.
---------------------------------
Resolution: Fixed
Merged in https://github.com/apache/camel/pull/28042 (commit 1239c76ac3c1), for
4.24.0. The hint for a Map or List as the platform-http response body, first
planned here, is covered by CAMEL-25751 and CAMEL-25749.

> camel-bean, camel-platform-http - the errors for a key read from a stream,
> JSON text or a List, and for a Map or List as the HTTP response, say what to
> do

> Key: CAMEL-25746
> URL: https://issues.apache.org/jira/browse/CAMEL-25746
> Project: Camel
> Issue Type: Improvement
> Components: camel-bean, camel-platform-http
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 4.24.0

>
> In the overnight benchmark of Oct 17-18 2026 (ten runs of a local model on
> the example ladder), 3 of the 8 failed steps of the contract-first openapi
> example hit errors that name the problem but not the fix:
> * "Key: qty not found in bean: ...ByteArrayInputStreamCache ... using OGNL
> path [[qty]]": a variable that holds the raw request body, because it was set
> before the body was unmarshalled.
> * "Key: qty not found in bean: [\{sku=CAMEL-TSHIRT, qty=120\}, ...] of type:
> java.util.ArrayList": a key read from the whole list before an element was
> picked.
> * "No type converter available to convert from type: java.util.ArrayList to
> the required type: java.io.InputStream": a List returned as the platform-http
> response.
> Proposal: a short hint after the message, as CAMEL-25309 did for the http
> producer:
> * A stream or bytes: the value is the message body as a stream, not a Map;
> unmarshal it first (for example with json), then read the key. A variable
> keeps the value it had when it was set.
> * JSON text: unmarshal it first.
> * A List: a List has no keys; pick an element first, such as [0][qty], or
> split the list.
> * A Map or List as a platform-http response body: marshal it to JSON first
> (marshal: json), or set the body to the JSON text.
