---------------------------------
Resolution: Fixed
> camel-rest-openapi - log the problems the OpenAPI parser finds in the
> specification
> -----------------------------------------------------------------------------------
>
> Key: CAMEL-25747
> URL: https://issues.apache.org/jira/browse/CAMEL-25747
> Project: Camel
> Issue Type: Improvement
> Components: camel-rest-openapi
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 4.24.0
>
>
> camel-rest-openapi loads the specification with the swagger parser, but it
> drops the messages in the parse result. The parser ignores the parts it
> cannot read, so a mistake in the contract leaves no trace in the log.
> Example: a path nested inside another path item.
> {code}
> "paths": {
> "/stock": {
> "get": { "operationId": "listStock", ... },
> "/stock/{sku}": {
> "get": { "operationId": "getStock", ... }
> }
> }
> }
> {code}
> The parser reports "attribute paths.'/stock'./stock/\{sku\} is unexpected"
> and ignores the nested path. The contract-first Rest DSL starts, but GET
> /stock/A1 answers 404, and nothing in the log says why. A local model wrote
> this contract in the overnight benchmark of Oct 17-18 2026 (see CAMEL-25746).
> Proposal:
> * Log the parser messages as a WARN when the specification is loaded. This
> covers the consumer (the contract-first Rest DSL) and the producer.
> * When the parser cannot read the specification at all, add its messages to
> the exception. Today it says only "Could not deserialize OpenAPI
> specification from: ...".
