If you are using Groovy component in you flow,then you can define sleep() as follow :-

<scripting:component doc:name="Groovy">
  <scripting:script engine="Groovy"><![CDATA[
    sleep(10000);
    return message.payload;]]>
  </scripting:script>
</scripting:component>

And remember to return message.payload in Groovy so that you can get the payload at the end or else you will get null payload

Groovy has an issue of loosing payload if you don't return at the end, so, in Groovy you need to return the payload at end, and that's the reason you are receiving null payload

Alternately you can use expression-component as follow:-

<expression-component>
    Thread.sleep(10000);
</expression-component>
