Spring Generic error when invalid json parsing/decoding happens in webflux

Affects: 2.6.1

I'm using starter-webflux, and when invalid json is sent to my service I get a super generic error:

{
  "timestamp": "2022-01-05T20:33:32.425+00:00",
  "path": "/pets",
  "status": 400,
  "error": "Bad Request",
  "message": "Failed to read HTTP message",
}

notes: - spring-boot-devtools is active - traces in responses is turned off - I would like to avoid all the package - info leaving my API

If I include a stacktrace in my response I see that this is a org.springframework.core.codec.DecodingException. It seems like when webflux is used the message of this exception is not being mapped to the error response from spring.

Is this something that I can fix in my app? Or is this something that is could be improved in springboot?

I've done some additional reading, and it seems like this still open ticket is very similar: https://github.com/spring-projects/spring-boot/issues/18815

It is, closing as a duplicate.

@snicoll any ideas on a resolution? I was able to do what was needed through @ControllerAdvice but something built into the framework would be sweet.
