hi, how do I customize Jackson for openapi generation? serializing "description": null seems illegal in many cases

[Stefan]

oh, I wasn't aware an object isn't a type itself in kotlin

[Stefan]

OpenAPI3(..., json = ConfigurableJackson( is valid

[dave]

I think it's only illegal in the swagger editor - not the spec or the Swagger UI.

[Stefan]

npx @redocly/openapi-cli lint ~/tmp/swagger.yaml also complains

[Stefan]

but let me see first, if that wasn't just because of other mistakes

[dave]

we've heard it before - so it's definitely "a thing". you can create your own instance of ConfigurableJackson to turn off the serialisation of nulls

[Stefan]

I'll do. Thank you

[dave]

FYI - as a part of our build, we already put generated APIs through the official OpenApi validator to generate a spec in v2 and v3 fotrmats

[Stefan]

nice- I hope I can check it out

[Stefan]

how can I add a description to the path parameters?

[Stefan]

ahh

[Stefan]

by not calling meta but as constructor arg
