oneOf only validates the schema but does not add missing field with default values.
I have defined this schema that selects a schema based on animal field and then validates the request body depending upon selected animal schema.
but this does not append the field with default values.
```
{
type: 'object',
discriminator: {
propertyName: 'animal',
mapping: {
cat: '#/oneOf/0',
dog: '#/oneOf/1'
}
},
oneOf: [
{
type: 'object',
required: ['name', 'age'],
properties: {
animal: {
type: 'string',
enum: ['cat']
},
isLazy: {
type: 'boolean',
default: true
},
name: {
type: 'string'
},
age: {
type: 'integer'
}
},
},
{
type: 'object',
required: ['breed', 'weight'],
properties: {
animal: {
type: 'string',
enum: ['dog']
},
isFriendly: {
type: 'boolean',
default: true
},
breed: {
type: 'string'
},
weight: {
type: 'number'
}
},
}
],
}here if i upload a request:
```
```
```
{
"animal": "cat",
"name": "Whiskers",
"age": 5
}
```
in this case isLazy field should get added with default value true to the req.body received by API.
i.e
```
i.e
```
{
"animal": "cat",
"isLazy": true,
"name": "Whiskers",
"age": 5
}
```
Can someone confirm if oneOf or discriminator only validates the request or does it also add default values like a normal schema.
i am using openapi: version 3.0.3 and express-openapi.
