I have a route that uses the camel-rest-openapi component to call an operation defined in the Petstore OpenAPI Spec. The component is appending the basePath multiple times when attempting to run the route causing a HTTP 404 response.
ex: petstore3.swagger.io /api/v3/api/v3 /pet/findByStatus?status=available
Below is the route definition using Yaml DSL and the output from camel jbang.
Route:
- from:
uri: "timer:fetchPets?repeatCount=1"
description: "Periodically fetches list of pets"
steps:
- to: "rest-openapi:https://petstore3.swagger.io/api/v3/openapi.json#findPetsByStatus?status=available&componentName=https"
- log: "Received pets list: ${body}"
Output log:

Note: Annotation processing is enabled because one or more processors were found
on the class path. A future release of javac may disable annotation processing
unless at least one processor is specified by name (-processor), or a search
path is specified (--processor-path, --processor-module-path), or annotation
processing is enabled explicitly (-proc:only, -proc:full).
Use -Xlint:-options to suppress this message.
Use -proc:none to disable annotation processing.

Attempted to use both v2 and v3 of the Petstore spec. Also tried to override the basePath in spec by setting the basePath property in application.properties and as a query parameter on the camel-rest-openapi component.
