How do I resolve this codec error when using Shedlock with mongo

Hi I am trying to use Shedlock for Spring Boot Mongo. The docs said it required Mongo JAva 3.7.0. I am currently using Spring spring-boot-starter-parent v 2.0.4, which had an older version of the driver, so upgraded to version 2.1.0.

Below is the code I have place to start the lock:

@Configuration
@EnableScheduling
@EnableSchedulerLock(defaultLockAtMostFor = "1m")
public class ApplicationConfiguration {

@Bean
public LockProvider lockProvider(MongoClient mongo) {
    return new MongoLockProvider(mongo.getDatabase("hmrccalculation"));
}
}

Then my code is:

@Scheduled(cron = "I 0 0/5 * * * *")
@SchedulerLock(name = "lock", lockAtLeastFor = "1m")
public void process() {
    LockAssert.assertLocked();

The error I get is:

"message":"Unexpected error occurred in scheduled 
task.","stack":"org.bson.codecs.configuration.CodecConfigurationException: Can\'t find a 
codec for class java.time.Instant.\nat 
org.bson.codecs.configuration.CodecCache.getOrThrow(CodecCache.java:46)\nat

You have to upgrade to mongo-java-driver 3.7.0. Spring Boot 2.1.0 contains an older version. You do not have to upgrade whole Spring Boot, just the one dependency.
