## API design principles
If a required schema property is declared but not defined, this rule informs you which of the required schema properties are missing.
## Configuration
| Option | Type | Description |
| -------- | ------ | ---------------------------------------------------------------------------------------- |
| severity | string | Possible values: `off`, `warn`, `error`. Default `off` (in `recommended` configuration). |
An example configuration:
```yaml
rules:
no-required-schema-properties-undefined: error
```
## Examples
Given this configuration:
```yaml
rules:
no-required-schema-properties-undefined: error
```
Example of **incorrect** schema properties:
```yaml
schemas:
Pet:
type: object
required:
- id
- name
properties:
id:
type: integer
format: int64
```
Expected error message when linting incorrect schema example:
```bash
Required property 'name' is undefined.
```
Example of **correct** schema properties:
```yaml
schemas:
Pet:
type: object
required:
- id
- name
properties:
id:
type: integer
format: int64
name:
type: string
example: doggie
```
The rule is case-sensitive, which means a property `name` does not match the string `Name` in the `required` list:
```yaml
schemas:
Pet:
type: object
properties:
name:
type: string
required:
- Name
```
