Scala codegen doesn't work with openapi petstore.yml

Using petstore.yml: https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/modules/openapi-generator/src/test/resources/3_0/petstore.yaml and https://github.com/guardrail-dev/guardrail-sample-sbt-http4s

works:

Then that unlocked a new error:

The utf8 and Multiparts issue is new, thanks for reporting! I've resolved that issue in the sample repo.

The default issue is unfortunate, since it's incorrect to assume that 100 and 500 have the same semantics.
