ReactiveRedisTemplate opsForValue().set not working

I am trying to save oauth login credentials in redis . Using spring oauth2 library, and spring redis.

My saveAuthorizedClient method should be saving the key/val pair in redis, but nothing is being saved. Have attached a debugger and the key value pairs are correctly assigned, its the reactiveOauthRedisTemplate.opsForValue().set(key, authorizedClient) which seems to be not doing anything.

class CustomClientService(        val reactiveClientRegistrationRepository: ReactiveClientRegistrationRepository,        val reactiveOauthRedisTemplate: ReactiveRedisTemplate<String, OAuth2AuthorizedClient>) : ReactiveOAuth2AuthorizedClientService {    override fun <T : OAuth2AuthorizedClient> loadAuthorizedClient(clientRegistrationId: String, principalName: String): Mono<T> {        Assert.hasText(clientRegistrationId, "clientRegistrationId cannot be empty")        Assert.hasText(principalName, "principalName cannot be empty")        return clientRegistrationRepository.findByRegistrationId(clientRegistrationId)                .map { rediskey(clientRegistrationId, principalName) }                .flatMap { key: String ->                    reactiveOauthRedisTemplate.opsForValue().get(key) as Mono<T>                }    }    override fun saveAuthorizedClient(authorizedClient: OAuth2AuthorizedClient, principal: Authentication): Mono<Void> {        val key = rediskey(authorizedClient.clientRegistration.registrationId, principal.name)        reactiveOauthRedisTemplate.opsForValue().set(key, authorizedClient)                .let {                    val x = reactiveOauthRedisTemplate.opsForValue().get(key)                    println("my redis data is $x")                    x.map {                        println("my data value is $it")                        val token = x as OAuth2AuthorizedClient                    }                }        return Mono.empty()    }    private fun rediskey(clientRegistrationId: String, principalName: String): String {        return "something..."    }}

Here's my redis config

@Configurationclass RedisConfig {    @Bean    fun reactiveOauthRedisTemplate(reactiveRedisConnectionFactory: ReactiveRedisConnectionFactory,                                   resourceLoader: ResourceLoader): ReactiveRedisTemplate<String, OAuth2AuthorizedClient> {        val keySerializer: RedisSerializer<String> = StringRedisSerializer()        val defaultSerializer = JdkSerializationRedisSerializer(resourceLoader.classLoader)        val serializationContext = RedisSerializationContext                .newSerializationContext<String, OAuth2AuthorizedClient>(defaultSerializer).key(keySerializer).hashKey(keySerializer)                .build()        return ReactiveRedisTemplate(reactiveRedisConnectionFactory, serializationContext)    }}

redis yaml config

spring:  redis:    host: localhost

From debugger , the redis connect has host and port correct. Any help here is appreciated.

Here's my redis client object from debugger

redisURI = {RedisURI@12018} "redis://127.0.0.1" host = "127.0.0.1" socket = null sentinelMasterId = null port = 6379 database = 0 clientName = null username = null password = null ssl = false verifyMode = {SslVerifyMode@12033} "FULL" startTls = false timeout = {Duration@12010} "PT1M" sentinels = {ArrayList@12034}  size = 0
