Question about ktor on App Engine standard.
What thread are requests dispatched on ? Because trying to use Any AppEngine APIs give me an exception.
For e.g.

get("/test") {
        val executor = Executors.newCachedThreadPool(ThreadManager.currentRequestThreadFactory())
        val scope = CoroutineScope(executor.asCoroutineDispatcher())
        scope.launch {
            val oauthScope = "<scope>"
            val accessToken = AppIdentityServiceFactory.getAppIdentityService().getAccessToken(listOf(oauthScope))
            call.respondText {
                accessToken.accessToken
            }
        }
    }

java.lang.NullPointerException: Current thread is not associated with any request and is not a background thread
