REST API creating document from an uploaded file fails with internal-error due to NPE

Hi, I am trying to upload a document to Nuxeo, which - according to the example in QA-Friday example is consisted of a 2-steps process:

the 1st step, of uploading the file(s), works fine
the 2nd step fails: I am trying to use the more capable API, which supports doc creation from multiple uploaded files (even though this test utilizes a single file), and as such - following the JSON structure and content of the example from QA-Friday:

curl -X POST -H "Content-Type: application/json" -u Administrator:Administrator -d '{
    "entity-type" : "document",
    "name" : "myNewDoc2",
    "type" : "File",
    "properties" : {
        "dc:title" : "My new doc2",
        "files:files" : [
            { "file" : { "upload-batch" : "mybatchid", "upload-fileId" : "0"}, "filename" : "myFile.zip"},
            { "file" : { "upload-batch" : "mybatchid", "upload-fileId" : "1"}, "filename" : "myOtherFile.zip"}
        ]
    }
}' http://localhost:8080/nuxeo/api/v1/path/default-domain/workspaces/workspace

my JSON looks like this:

{ 
    "entity-type" : "document", 
    "name" : "UploadedFile00.txt",
    "properties" : {
        "dc:title" : "UploadedFile00.txt",
        "files:files" : [ {
            "file" : {
                "upload-batch" : "batchId-0d6800c3-6a8d-4c23-9361-4477dbe1376e",
                "upload-fileId" : "0"
            },
            "filename" : "UploadedFile00.txt"
        } ]
   },
   "type" : "file"
 }

(with its details based on 1st/upload step) and yet it fails: response.toString():

And server.log:

Any idea what I am doing wrong/missing ?

Found the issue: my JSON (above) spelled

"type" : "file"

instead of

"type" : "File"
