## RestHttpErrors.ValidationErrorDetails interface

An invalid request body error contains a `details` property as the machine-readable error. Each entry in `error.details` contains 4 attributes: `path`<!-- -->, `code`<!-- -->, `info` and `message`<!-- -->. `ValidationErrorDetails` defines the type of each entry, which is an object. The type of `error.details` is `ValidationErrorDetails[]`<!-- -->.

**Signature:**

```typescript
interface ValidationErrorDetails 
```
