How to force readEntity using Jackson in REST Client Reactive when returned content-type is text/plain?

[astappiev]

I'm building a REST Client Reactive for a quite old API endpoint, which supports json format, however, it returns an incorrect header - Content-type: text/plain;charset=utf-8.

When I'm trying to return an entity, it throws jakarta.ws.rs.ProcessingException: Response could not be mapped to type class IpernityResponse.

Is there a way to add custom MessageBodyReader or modify response headers before reading?
Right now, I return String from a client and then use ObjectMapper to successfully read it.

Thank you in advance

You can try playing with a ReaderInterceptorContext which you can register as a provider.
