Hi,
I'm testing the Camel JBang 3.20 OpenAPI to REST generator and
encountering some issues with enums when trying to run the generated
file. The schema in the error message looks peculiar when trying to
run the XML DSL as it points to spring but I'm not sure if it should
look like that.
Error with XML Rest DSL:
org.apache.camel.RuntimeCamelException:
org.apache.camel.xml.io.XmlPullParserException: Unexpected element
'{http://camel.apache.org/schema/spring}allowableValues'
Error with YAML Rest DSL:
Unsupported field: allowableValues
in file:myroutes.yaml, line 124, column 11:
value:
More information follows:
I'm using the PetStore OpenAPI 3 spec:
https://github.com/swagger-api/swagger-petstore/blob/master/src/main/resources/openapi.yaml
I'm generating the REST DSL using:
camel generate rest -i openapi.yaml -o myroutes.yaml
The generation goes through without errors. But Camel isn't able to
parse the generated file when trying to run the routes using camel run
myroutes.yaml:
---
Unsupported field: allowableValues
in file:myroutes.yaml, line 124, column 11:
value:

The generated file contains this which based on the error is failing:
get:
- id: "findPetsByStatus"
path: "/pet/findByStatus"
description: "Multiple status values can be provided with comma
separated strings"
produces: "application/xml,application/json"
param:
- dataType: "string"
defaultValue: "available"
description: "Status values that need to be considered for filter"
name: "status"
required: false
type: "query"
allowableValues:
value:
- "available"
- "pending"
- "sold"
to: "direct:findPetsByStatus"
The original OpenAPI spec has this:
/pet/findByStatus:
get:
tags:
- pet
summary: Finds Pets by status
description: Multiple status values can be provided with comma
separated strings
operationId: findPetsByStatus
parameters:
- name: status
in: query
description: Status values that need to be considered for filter
required: false
explode: true
schema:
type: string
enum:
- available
- pending
- sold
default: available
I also tried generating XML DSL and it gives the following error when running:
org.apache.camel.RuntimeCamelException:
org.apache.camel.xml.io.XmlPullParserException: Unexpected element
'{http://camel.apache.org/schema/spring}allowableValues'
I tried to find the relevant parts from the Apache Camel's source code
and AFAIK it tries to handle allowableValues. The schema in the XML
error looks strange though with a reference to spring. Should that be
rest instead?
Everything works OK with a simpler schema
(https://github.com/OAI/OpenAPI-Specification/blob/main/examples/v3.0/petstore.yaml)
Is this a known issue or is there some setting I could change to make
things work? Thanks in advance!
Best regards,
Mikael
