I tried to run the box connector after importing the project from github https://github.com/mulesoft/box-connector project running successfully but after grant permission, I am getting the following error,

Unable to fetch access token. Message payload is of type: NullPayload

Its working for me without issues. Anyway below is the my working POC code XML. Give a try with this and note that I am using Mule 3.5.2 run time version

<box:config name="Box_Global_Connector" clientId="*********"
    clientSecret="********" doc:name="Box">
    <box:oauth-callback-config domain="localhost"
        localPort="8083" path="callback" remotePort="8083" />
</box:config>
<flow name="mule_box_authorize" doc:name="mule_box_authorize">
    <http:inbound-endpoint exchange-pattern="request-response"
        host="localhost" port="8082" path="createFolder" doc:name="HTTP" />
    <logger message="---- Box authorize service triggred" level="INFO"
        doc:name="Logger" />
    <box:authorize config-ref="Box_Global_Connector"
        doc:name="Box_Authorize" />
    <box:create-folder config-ref="Box_Global_Connector"
        folderName="Sample_Folder_07Oct2015_v2" doc:name="Box_CreateFolder" />
</flow>

Recently I did a POC on Integrating Mule ESB with Box using Mule Box Connector and made a PPT on this. Just go through the below slidshare PPT for more details

http://www.slideshare.net/RamakrishnaNarkedami/mule-integration-with-box

Also Share your mule config XML code to see where is the issue.

The below code will work fine with version 3.7.2 

<http:listener-config name="HTTP_Listener_Configuration" host="0.0.0.0" port="8081" doc:name="HTTP Listener Configuration"/>
<box:config name="Box" clientId="05zpeboxxfms6fo7805izrxff9dwbc74" clientSecret="LVD5juoF7ookFVn4uN69Pco3NI4EQeE0" doc:name="Box">
    <box:oauth-callback-config domain="localhost" localPort="8082" remotePort="8082" path="callback"/>
</box:config>
<objectstore:config name="ObjectStore__Configuration" objectStore-ref="_defaultInMemoryObjectStore" doc:name="ObjectStore: Configuration" />
<flow name="boxAuthenticationFlow">
    <http:listener config-ref="HTTP_Listener_Configuration" path="/auth" doc:name="HTTP"/>
    <box:authorize config-ref="Box" doc:name="Box-Authorize"  />
</flow>
