How to download a document from Alfresco CMIS

Hello,
I have been able to create a folder in Alfresco from Bonita CMIS connector.
I have also been able to upload a document from Bonita to Alfresco.

But I am not able to download a document.  I am getting the below error. 
Is there any documentation available for Document download.
