OpenAPI spec using allOf to override inherited property - jsonschema

Question

I am attempting to run an existing OpenAPI schema through Open API Enforcer and I am getting various validation errors in the usage of allOf. One such usage is described below:
Consider the following property in a schema:
queryVersion:
allOf:
- $ref: 'VersionDefinition.yaml'
- description: >-
This is my overriding version
VersionDefinition.yaml is defined as follows:
description: >-
Some default version description.
type: string
default: '5.2'
There are two issues with the above definition:
OpenAPI Enforcer expects all schemas defined within allOf or similar keyword to start with a type definition. So, the error it spits out is:
at: queryVersion > allOf > 1
Missing required property: type
I fix that by modifying the allOf definition as follows:
queryVersion:
allOf:
- $ref: 'VersionDefinition.yaml'
- type : object
properties:
- description: >-
This is my overriding version
That eliminates the error but what should I expect to see in the generated schema? Original author indicates he is using allOf to override the property description. However, the generated schema includes this result:
"queryVersion": {
"allOf": [
{
"description": "Some default version description",
"type": "string",
"default": "5.2"
},
{
"type": "object",
"properties": [
{
"description": "This is my overriding version"
}
]
}
]
}
What I expected to see was:
"queryVersion": {
"description": "This is my overriding version",
"type": "string",
"default": "5.2"
}
I'll keep digging but any ideas?
