From Spring Boot 3.2.4, CoroutineCrudRepository raises a CalssCastExceptionc(class kotlin.reflect.jvm.internal.KTypeParameterImpl cannot be cast to class kotlin.reflect.KClass) with Reactive MongoDB.

Until 3.2.3, there is no problem, but after upgrading to 3.2.4, whenever I try to handle a single entity(findById, save, ...) a ClassCastException is thrown.
I created a simple demo project from "https://start.spring.io", wrote very simple codes, and tested. I attached the project. I use MongoDB 7.0.4.

It should be. I'm moving this to Framework for consideration.

I created a simple demo project from "https://start.spring.io/", wrote very simple codes, and tested. I attached the project. I use MongoDB 7.0.4.

Thanks but as simple as you may think it is, it does not work without MongoDB running locally. Care to provide what we should run (e.g. docker) to actually be able to use the sample? If we need to execute something against the app, a request sample would also be appreciated.

It seems like "id" might be a reserved word.

example code

interface Repository : CoroutineCrudRepository<Person, Int> {
    // same error
    @Query("UPDATE person set age = 1 where id = :id")
    suspend fun update(id: Int)

    // it works
    @Query("UPDATE person set age = 1 where name = :name")
    suspend fun update(name: String)
}
