ADL LRS saves statement but responds with HTTP 500

Question

I've installed ADL LRS following README.txt on https://github.com/adlnet/ADL_LRS.

I'm testing it with TincanJS (https://github.com/RusticiSoftware/TinCanJS) with following code, statement gets saved but response code is 500.

lrs = new TinCan.LRS(
        {

            ////// This works well
            endpoint: "https://cloud.scorm.com/tc/public/",
            username: "<Test User>",
            password: "<Test Password>",
            allowFail: false

            ////// This returns Internal Error(500)
            endpoint: "my.server:8000/xapi/",
            username: "<My User>",
            password: "<My Password>",
            allowFail: false
        }
);

var statement = new TinCan.Statement(
        {
            actor: {
                "name": "Ac Tor",
                "account": {
                    "homePage": "http://act.or",
                    "name": "actor"
                }
            },
            verb: {
                id: "http://adlnet.gov/expapi/verbs/experienced"
            },
            target: {
                id: "http://rusticisoftware.github.com/TinCanJS"
            }
        }
);

lrs.saveStatement(
        statement,
        {
            callback: function (err, xhr) {
                //...
            }
        }
);

Thanks in advance.

Answer 1

There are log files in the log/ folder created during installation of the LRS. Inside there is an lrs.log file that will tell you what is causing the 500 error. I was able to send statements to a local LRS instance with no 500 error. Please respond back with the error so I can help. Thanks

Answer 2

Unless this is just a quirk of TinCanJS, I would think target should be object.
