Hi, can someone help figuring out what is going wrong with this test <https://stackoverflow.com/questions/72520472/ktor-testing-fail-to-serialize-body-content-has-type-class-but-outgoingcon>
Thanks in advance

I'd say you're missing the `ContentNegotiation` plugin in your client.

It's actually telling you in the error message
```If you expect serialized body, please check that you have installed the corresponding plugin(like `ContentNegotiation`) and set `Content-Type` header.```
