tMongoDBOutput - Configuring JSON tree

Question

Trying to configure JSON tree for tMongoDBOutput. Only 1 element is getting created in subelement array. Can someone please give a example of configuring the JSON tree. Requirement is one document can have multiple nested sub documents. Medical_records can have multiple sub documents, but only 1 sub document is getting created now skipping the rest.

Resulting JSON in MongoDB as follows

{
"first_name" : "testname",
"middle_name" : [],
"last_name" : "test",
"medical_records" : [ 
    {
        "dateofuploading" : "2016-09-29 12:49:21.5",
        "filename" : "demo.pdf",
        "isautogenerated" : "1",
        "recordid" : "123"
    }
]

}
