It seems like there is nothing to do here.

If params is not required then we get validation error:

```
Array
(
    [openApiPath] => Array
        (
            [0] => Failed to validate OpenAPI spec:<ul>
<li>[/paths/~1pets~1{id}/get/parameters/1] Parameter &#39;required&#39; must be true for &#39;in&#39;: &#39;path&#39;.</li>
</ul>
        )

)
```

and code generation fails.
