`chatClient…entity(Foo::class.java)` in Kotlin doesn’t work with Kotlin data classes when it does work in Java records

[joshlong]

I'm afk but I got an error trying to deserialize a Kotlin data class using the ChatClient's entity(Class<T>) method

try register jackson kotlin module, at least it works for me. essentially kotlin's data class compiles into a class with a full-parameter constructor. register relevant module should resolve the issue

add dependency:

<dependency>
    <groupId>com.fasterxml.jackson.module</groupId>
    <artifactId>jackson-module-kotlin</artifactId>
</dependency>

ObjectMapper register module:

OBJECT_MAPPER.registerModule(new KotlinModule.Builder().build())
