When I use http4k-contract to generate a spec, the path and query descriptions are serialized as

null

with both Argo and Jackson. The Swagger Editor seems to treat these as warnings, Swagger UI works fine, but the latest Redoc throws an exception that prevents the UI from loading. Is there any way to set a non-null description for these parameters? Or has anyone had a better experience with a different version of redoc?

We a using a custom configuration of Jackson for avoiding sending the null values

renderer = OpenApi3(
                        ApiInfo("xxx API", "1.x", "desc"),
                        AppJackson,
                        apiRenderer = ApiRenderer.Auto(AppJackson, auto),
                    )

with:

object AppJackson : ConfigurableJackson(
    KotlinModule()
        .asConfigurable()
        .withStandardMappings()
        .done()
        .deactivateDefaultTyping()
        .configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false)
        .configure(DeserializationFeature.FAIL_ON_IGNORED_PROPERTIES, false)
        .configure(DeserializationFeature.USE_BIG_DECIMAL_FOR_FLOATS, true)
        .configure(DeserializationFeature.USE_BIG_INTEGER_FOR_INTS, true)
        .setSerializationInclusion(JsonInclude.Include.NON_NULL)
)
