[Bug]: Generated openapi schema has validation errors

[haringsrob]

Steps to reproduce

On the server head to /openapi.json on the host path.

Actual behaviour

There is a v3.1.0 openapi schema. But when building an sdk with https://github.com/OpenAPITools/openapi-generator the resulting code (in my case rust) various validation errors occur.

Also opening it in https://editor-next.swagger.io/ shows various validation issues.

Expected behaviour

The api should validate without issues so that sdk's can be generated.
