Unable to post xAPI statement into a newly installed LL on Amazon EC2

[Nadav Kavalerchik]

Following the instructions on:

http://cloudboffins.com/advanced-projects/learning-locker-lrs-free-server-part-1/

I have successfully installer a LL on an Amazon EC2 server.

Everything seems ok but...

When generating a statement on

http://tincanapi.com/statement-generator/

{

    "actor": {

        "mbox": "mailto:myemailw...@gmail.com",

        "name": "First Last",

        "objectType": "Agent"

    },

    "verb": {

        "id": "http://adlnet.gov/expapi/verbs/completed",

        "display": {

            "en-US": "completed"

        }

    },

    "object": {

        "id": "http://www.example.com/tincan/activities/jozcodRk",

        "objectType": "Activity",

        "definition": {

            "name": {

                "en-US": "Example Activity"

            },

            "description": {

                "en-US": "Example activity definition"

            }

        }

    }

}

And sending to over to my new LL, I get the following error message.

{"error":true,"message":"","code":404,"trace":[{"file":"\/var\/www\/learninglocker\/vendor\/laravel\/framework\/src\/Illuminate\/Routing\/Router.php","line":1021,"function":"match","class":"Illuminate\\Routing\\RouteCollection","type":"->","args":[{"attributes":{},"request":{},"query":{},"server":{},"files":{},"cookies":{},"headers":{}}]},{"file":"\/var\/www\/learninglocker\/vendor\/laravel\/framework\/src\/Illuminate\/Routing\/Router.php","line":989,"function":"findRoute","class":"Illuminate\\Routing\\Router","type":"->","args":[{"attributes":{},"request":{},"query":{},"server":{},"files":{},"cookies":{},"headers":{}}]},{"file":"\/var\/www\/learninglocker\/vendor\/laravel\/framework\/src\/Illuminate\/Routing\/Router.php","line":968,"function":"dispatchToRoute","class":"Illuminate\\Routing\\Router","type":"->","args":[{"attributes":{},"request":{},"query":{},"server":{},"files":{},"cookies":{},"headers":{}}]},{"file":"\/var\/www\/learninglocker\/vendor\/laravel\/framework\/src\/Illuminate\/Foundation\/Application.php","line":738,"function":"dispatch","class":"Illuminate\\Routing\\Router","type":"->","args":[{"attributes":{},"request":{},"query":{},"server":{},"files":{},"cookies":{},"headers":{}}]},{"file":"\/var\/www\/learninglocker\/vendor\/laravel\/framework\/src\/Illuminate\/Foundation\/Application.php","line":708,"function":"dispatch","class":"Illuminate\\Foundation\\Application","type":"->","args":[{"attributes":{},"request":{},"query":{},"server":{},"files":{},"cookies":{},"headers":{}}]},{"file":"\/var\/www\/learninglocker\/vendor\/asm89\/stack-cors\/src\/Asm89\/Stack\/Cors.php","line":51,"function":"handle","class":"Illuminate\\Foundation\\Application","type":"->","args":[{"attributes":{},"request":{},"query":{},"server":{},"files":{},"cookies":{},"headers":{}},1,true]},{"file":"\/var\/www\/learninglocker\/vendor\/laravel\/framework\/src\/Illuminate\/Http\/FrameGuard.php","line":38,"function":"handle","class":"Asm89\\Stack\\Cors","type":"->","args":[{"attributes":{},"request":{},"query":{},"server":{},"files":{},"cookies":{},"headers":{}},1,true]},{"file":"\/var\/www\/learninglocker\/vendor\/laravel\/framework\/src\/Illuminate\/Session\/Middleware.php","line":72,"function":"handle","class":"Illuminate\\Http\\FrameGuard","type":"->","args":[{"attributes":{},"request":{},"query":{},"server":{},"files":{},"cookies":{},"headers":{}},1,true]},{"file":"\/var\/www\/learninglocker\/vendor\/laravel\/framework\/src\/Illuminate\/Cookie\/Queue.php","line":47,"function":"handle","class":"Illuminate\\Session\\Middleware","type":"->","args":[{"attributes":{},"request":{},"query":{},"server":{},"files":{},"cookies":{},"headers":{}},1,true]},{"file":"\/var\/www\/learninglocker\/vendor\/laravel\/framework\/src\/Illuminate\/Cookie\/Guard.php","line":51,"function":"handle","class":"Illuminate\\Cookie\\Queue","type":"->","args":[{"attributes":{},"request":{},"query":{},"server":{},"files":{},"cookies":{},"headers":{}},1,true]},{"file":"\/var\/www\/learninglocker\/vendor\/stack\/builder\/src\/Stack\/StackedHttpKernel.php","line":23,"function":"handle","class":"Illuminate\\Cookie\\Guard","type":"->","args":[{"attributes":{},"request":{},"query":{},"server":{},"files":{},"cookies":{},"headers":{}},1,true]},{"file":"\/var\/www\/learninglocker\/vendor\/laravel\/framework\/src\/Illuminate\/Foundation\/Application.php","line":606,"function":"handle","class":"Stack\\StackedHttpKernel","type":"->","args":[{"attributes":{},"request":{},"query":{},"server":{},"files":{},"cookies":{},"headers":{}}]},{"file":"\/var\/www\/learninglocker\/public\/index.php","line":49,"function":"run","class":"Illuminate\\Foundation\\Application","type":"->","args":[]}]}

Not sure what's wrong with LL

Any ideas?

What endpoint are you using? Does it have a slash at the end?

[Nadav Kavalerchik]

Yes :-) Of course :-)

This is my endpoint

http://learninglocker.moodlemagic.info/data/xAPI/

​(I can open a new admin user for you if you'd like)​

I am also using the demo endpoint

​ from http://demo.learninglocker.net/

And while the Storyline Tincan package launches successfully from moodle (Your mod_launchtincan)

After it start to play (on a new browser tab) ​I am starting to get "400 errors"

Switching to WAXLRS, everything works fine.

​How do you suggest I debug it?​

Storyline uses a beta version of Tin Can (0.9) which learning locker doesn't support. Really articulate need to sort that out. Other authoring tools support 1.0.x.

For your hosted locker, I'll have a proper look at the error message later. It's quite hard to read on my phone.

Andrew

[Nadav Kavalerchik]

Thanks!

What xAPI authoring tool do you recommend?

(Do you know of any open source xAPI authoring tools?)

[Andrew Downes]

My company, LTG, makes an authoring tool called gomo, which of course is what I recommend ;-) Tin Can support is road mapped for October.

Both Captivate and Lectora have some Tin Can support and use 1.0.x.

Andrew

[Nadav Kavalerchik]

Does Gomo support RTL (and Hebrew) ?

Andrew

[Andrew Downes]

Good question. I'll find out.

[Andrew Downes]

Hi,

I've had a look at the error and had a poke at your LRS and can't see anything obvious. 

When I try with the tool here: http://garemoko.github.io/tinStatement/tinstatement.htm I get 401 unauthorized, which is what I expect and suggests the end point is working. 

Can you set me up with a set of credentials and I'll poke it further?

Andrew

[Nadav Kavalerchik]

Thank you for testing!

Sent you an invite for Super Admin :-)

Found the problem. It turns out the generator at http://tincanapi.com/statement-generator/ needs the endpoint without the slash. 

[Nadav Kavalerchik]

Bless you :-)
