I am getting this exception while storing a Boolean.

My redis config:

ReactiveRedisTemplate<String, Object> reactiveRedisTemplateGeneric(ReactiveRedisConnectionFactory reactiveRedisConnectionFactory) {
    GenericJackson2JsonRedisSerializer valueSerializer = new GenericJackson2JsonRedisSerializer();
    RedisSerializationContext.RedisSerializationContextBuilder<String, Object> builder =
            RedisSerializationContext.newSerializationContext(new StringRedisSerializer());
    RedisSerializationContext<String, Object> context = builder.value(valueSerializer).build();
    return new ReactiveRedisTemplate<>(reactiveRedisConnectionFactory, context);
}

We need to set serializer in the hashValue as well while building the context..

RedisSerializationContext<String, Object> context = builder.value(valueSerializer).hashValue(valueSerializer).build();
