This seems to happen any time a openapi enum is used, i.e.
ExampleResponse:
type: object
properties:
format:
$ref: "./components/schemas/ExampleEnum"
...
```yaml
ExampleEnum:
type: string
enum: ["binary", "text"]
description: "Type of data supported; Either binary or text."Setting either option to false avoids the crash.`
