title: ReactiveMongoRepository not saving my data
body: <p>I am noob in <code>spring</code> and <code>mongo</code> and <code>noSQL</code>.</p>
  
  <p>I have connected to my mongoDB on local. </p>
  
  <p>However my attempts to save my entity keeps failing.</p>
  
  <pre><code>val a0 = myEntity(name = "my Entity")
  repository.save(a0)
  </code></pre>
  
  <p>My repository extends <code>ReactiveMongoRepository&lt;MyEntity, Long&gt;</code>.</p>
  
  <p>But when I change it to extend <code>MongoRepository&lt;MyEntity, Long&gt;</code>, then it works.</p>
  
  <p>What possibly could be the problem?</p>
  
  <p>My database instance is running and working fine.
  I am guessing that it has to do something with reactive things.</p>
