Also, how do I add extension with an URI to the export query? I.e.

"context": {
      "extensions": {
        "https://www.paediatriccoughapp.com/extension/nickname": "FightingCough",
        "https://www.paediatriccoughapp.com/extension/specialty": "MyNick",
        "https://www.paediatriccoughapp.com/extension/country": "Germany"

And is there any way to amends existing statements on the LRS?

I have a question plz.
In an xAPI statement, I am using the "result" property. Inside it I use "completion", "success", {"score": raw,max,min,scaled}.
My question is how represent it in the xAPI profile. I have search some profiles in "Github ADL xapi" profiles but I didn't find an example to that.

@AVTPJ am not expert in LRSs but I think you have to go through mongodb collections and edit it from there.

Hello all. I have installed LL on my ubuntu machine and every thing is ok. But when I try to send an xAPI statements to the LRS, I find that the statements are not sent. The browser debugger shows the following err:
'POST http://localhost/data/xAPI/statements 500 (Internal Server Error)
ADL.XHR_request @ xapiwrapper.js:1525
XAPIWrapper.sendStatement @ xapiwrapper.js:331
sendStatement @ interaction.js:41
onclick @ index.html:39'

I tried using SCORM LRS , there everything goes well.
Help plz

@ht2 The Learning Locker Aggregation API documentation does not say anything about the MongoDB pipeline stages $merge nor $out. How do I get a LearningLocker dashboard to show the result of an aggregation done using the API?

Hi All

I have a Q plz. In tincan which activity type best describes a course units. For example, If I have a course containing 5 units and I want to track to learner's progress by measuring the units he completed. Which "ActivityType" better describes these units.

Thanks

gamahachaa

@gamahachaa

@khalidreemy this really depend on what you define as unit. the tincan registry lists all the basic activity types. For something usable in a curriculum and that contains different sub-content "http://adlnet.gov/expapi/activities/course" fits well. Look at https://registry.tincanapi.com/ to get inspired.

Hello, I would like to send my students from M365 to a test consisting of various H5P elements (hosted on a wordpress or moodle site, maybe) and ultimately analyse the results in M365. So, I'm wondering if I need to go through an LRS like LearningLocker to get the results from H5P and send them as an HTTP Post to M365, or if there is an easier way to accomplish that.

Khalid Yousif

@khalidreemy

@gamahachaa , @marcodalcolle_twitter
I mainly use "http://adlnet.gov/expapi/activities/course" as a reference but I couldn't find an "ActivityType" that matches a "Unit" of a course.

gamahachaa

@gamahachaa

@khalidreemy then http://adlnet.gov/expapi/activities/module "A module represents any "content aggregation" at least one level below the course level. Modules of modules can exist for layering purposes. Modules are not content. Modules are one level up from all content." sounds like it no ?

Khalid Yousif

@khalidreemy

@gamahachaa . you are right. I think I will use "module"

Hi there. The docs says Node version should be V10. I am upgrading my servers and V10 is deprecated. Which version are you guys running ? any one has experience running LL with V12 ?

Haakon Meland Eriksen

@HaakonME

Previous dialogue about xAPI profiles suggest these are not supported as something you can apply using LL directly by pointing to a file or URL, or it may be supported under an older term of "recipes", I am not sure - see http://docs.learninglocker.net/guides-inserting/#create-recipes . Yet Analytics LRS Pipe at https://github.com/yetanalytics/xapipe/ seems to be a way to specify an existing xAPI profile and then filter incoming or outgoing / forwarded statements through it to ensure the data conforms to the xAPI profile. This would be a handy improvement of LL, which could be applied to prevent none-conforming statements from entering LL, during processing inside LL as part of a pipeline, or during export / forwarding. Is something like it planned or in the works?

Haakon Meland Eriksen

@HaakonME

I need to filter by seconds and minutes, rather than hours.

It can be done in the code view of the Data > Source > Query Builder / Statement Explorer by dropping $dte from the query, e.g. the below query, which gives statements within the same second at millisecond precision.

Are there plans to include minutes and seconds in the UI?

Also, it is a bit of dark art to find out how $dte really works, as it seems to not like short periods of time. The same query as below with $dte will briefly flash a pink error message. Z-index is wrong, so partially obscured at the top of the UI.

I found the error message in the browser console: ' Cast to date failed for value "Invalid Date" at path "timestamp" for model "Statement" '. I suspect the reference to "model" is down to the Mongoose model, and the short time interval fails validation?

Is there some documentation of what $dte and other operators allow?

{
"$and": [
{
"$comment": "{\"criterionLabel\":\"A\",\"criteriaPath\":[\"timestamp\"]}",
"timestamp": {
"$gte": "2021-12-29T11:28:27.922Z",
"$lt": "2021-12-29T11:28:27.999Z"
}
}
]
}

Finally, is there a way I can ask for NOW or currentMoment minus some timeframe, e.g. NOW minus 10 seconds? Thank you for any help on this. :-)

Hi, I am running a docker instance and I haven't run it in a while. When I am trying to login I get 504 gateway timeout and the following error is shown: There was an error communicating with the login server.
I am running v2.8.2. I am getting the following from nginx docker instance: nginx_1 | 2022/01/08 12:15:25 [error] 8#8: *26 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 172.19.0.1, server: localhost, request: "POST /api/auth/jwt/password HTTP/1.1", upstream: "http://172.19.0.7:3000/api/auth/jwt/password", host: "localhost", referrer: "https://localhost/login"
I am sorry, I am new with xAPI and lrs and I am not sure how to solve it..

Aleksandra

@leksi37

I fixed it by following the following steps:

docker-compose down
Clear the $DATA_LOCATION directory
docker-compose up -d mongo and then observe docker-compose logs -f mongo, and wait until it gets ready
docker-compose up -d to bring up all the other services

Hi. I set up a multiple response survey for a client and successfully tested 1. posting the statement, 2. getting its id and 3. patching metadata on a local LL instance. The client is using enterprise though and I do not have access to their account (only base auth). I can post statements, but I can not get the id I need to patch the metadata: "message":"Privileges not sufficient for this operation" (request/response). Is this something the clients needs to set up in the web client or is the XHR flawed?

Dominik Rosehnal

@lincore81

To answer my own question: The client scope was limited to write access, after enabling read access it works as intended.

Hi folks, I am running some old Learning Locker v 3.18 or so, and Mongo 3.6. For an upgrade path: can we upgrade to version 4 then 5 then 6, or can we upgrade to a version 6 or 7 more direct approach?

njimkolp

@njimkolp

Hello, We are using Storyline 3.10 on Learning Locker v6.4.0. When the update for Storyline 3.11 was available. Our Learning Locker stopped writing the xAPI statements to the Mongo database. Has anyone else had this issue? Is it how Storyline 3.11 is publishing the courses? Or, do we need to update Learning Locker?

njimkolp

@njimkolp

I have an update. I looked at the changes made to Storyline 3.11. One of the changes was adding a second "identify the launch file". Is there somewhere in Learning Locker that the file is set?

gamahachaa

@gamahachaa

@jbiancot_twitter For Mongo you need to upgrade by .2 version step by step first, then upgrade your node (to 10) then LL with Pm2.

@njimkolp

Hello,

We have Learning Locker v6.4.0 "{"X-Experience-API-Version":"1.0.3","version":["1.0.3"]}". It does not seem to work well with the newest version of Articulate Storyline. Is Learning Locker able to work with bootstrapper.min.js? If so, what version?

Florian Tolk

@FlorianTolk

Are you sure you are using node 10? It is a fairly old version of nodejs, and has recently been deprecated.
I am in the process of trying to get it to run in a docker container with 12 and am running into the same problem. node-gyp has a number of odd requirements, like make and python being installed.

Hi, referring to "Statement Forwarding", is there anything like a "State Forwarding" feature? Or how can states be forwarded to another LRS?

There is other online community, e-mail, etc.. to get support for the Learning Locker software?

gamahachaa

@gamahachaa

It seems that nobody from the learning pool will ever appear and provide support again here. They seem to have changed their strategy. Last appearance from a @ryansmith94 was 2 years ago. I can understand though that support on opensource project cannot be forever free, considering the amount that was provided in the first years. But I agree it is a little disappointing to post an issue and have unanswered.

Florian Tolk

@FlorianTolk

I am trying to containerize and scan LearningLocker, however most of the unit tests are failing for the learningLocker base repo (all but one are passing for the service)
Is there documentation on why tests like "BatchDeleteController intialise should initialise a deletion with the correct filer"?

Florian Tolk

@FlorianTolk

I have also been struggling with this error on startup:
uncaughtException: listen EADDRINUSE: address already in use undefined

But I have defined every variable in the sample env file, so am unsure where this error is coming from

David Pesce

@davidpesce

I think it’s safe to say that the oss version of learning locker is dead. Take a look at YetAnalytics open source LRS as an alternative

Florian Tolk

@FlorianTolk

Will do. While I asses I do think I am closer to finding a solution.
Does anyone know what arguments to add to the .env file to pass in service bus settings?
uncaughtException: Cannot find correct Service Bus settings in configuration or environment

Hi Learning Locker team and people! I recently upgraded my LL installation from version 4.10.0 to the most recent version. Everything was good at upgrading but I cannot see the updated version on the login screen. The login screen keep displaying version 4.10.0. Is this an issue? Thank you!

Hi, guys. We have a problem with Redis on Azure because the number of connected clients just goes up and up, until it reaches the limits of connections. It looks like Learning Locker is opening connections but never closing them. Any ideas?

Hey, in some learning lockers the cursor parameter causes a 500-error: "A server error occurred".
Can i change something in the settings? In other LL the cursor parameter is working as intended. (tried out multiple with postman)
