I’m trying to create Micronaut bean with @RequestScope, but with each injection, there is a new instance created. I would expect it to create new instance only once per request.

Here is an example code:

@RequestScope
class RequestContext {
    var foo: String? = null
}

@Controller("/example")
class ExampleController(
    val requestContext: RequestContext,
    val exampleService: ExampleService
) {
    @Get()
    fun example() {
        requestContext.foo = "foo"
        exampleService.example()
    }
}

@Singleton
class ExampleService(
    val requestContextProvider: RequestContext
) {
    fun example() {
        println(requestContextProvider.foo) // prints nul instead of "foo"
    }
}

I have also tried wrapping RequestContext in Provider like here: micronaut @RequestScope – not creating bean per incoming http-request
but it changes nothing.

What am doing wrong?
How can I properly inject RequesScope bean into Singleton?

Micronaut Version: 4.5.1
