Initially reported in #860 (comment).

Calling client generated with the sample: https://github.com/CodeQualIT/CQITFunctions, causes feign.codec.EncodeException: Could not write request: no suitable HttpMessageConverter found for request type [nl.cqit.function.poc.java.helloworld.api.model.Person] and content type [application/json].

Possibly related to class generation.
