Snake case and discriminator config ignored

Tapir version: 1.10.12

Scala version: 2.13

I created a simple http post endpoint that receives a json request and produces a json response. It uses schema derivation to map the request and response to case classes.
i added implicit config to use discrinator and snake case members

‘’’

implicit val customConfiguration: Configuration =
Configuration.default.withDiscriminator(“type_discriminator”).withSnakeCaseMemberNames
‘’’

What is the problem?

The discriminator and snake case work in openapi spec generation but they are completely ignored for zio http server interpretation https://tapir.softwaremill.com/en/latest/server/ziohttp.html

How to reproduce?
Apply the implicit config to a tapir endpoint with schema/json derivation and run it in zio server interpreter.

Maybe you can provide code to reproduce the problem?

Additional information

Start by reproducing the schema- and JSON-derived endpoint with the supplied Scala Configuration and the ZIO HTTP server interpreter. Compare the generated OpenAPI behavior with request decoding and response encoding; done means the discriminator and snake_case member configuration are honored by the server interpreter as well.
