Getting 401 Unauthorized for xAPI response

[ksourabh45]

Hi all,

I have setup learning locker on EC2 instance and trying to insert xAPI statements but getting 401 Unauthorized error.

I have setup store and client as required and also added Basic Authorization header but getting error while trying to insert statements through postman.

Added screenshot below:

Please help me in resolving the issue.

Thanks in advance.

@ksourabh45 have you selected the store in the clients xAPI section?

On Settings -> Clients expand the client you are trying to use and check that your store is selected here (will say LRS (optional) in grey if not):

Hi @ToranSharma , Thanks for your response.

Yes it has store selected.

你好@ToranSharma， 感谢您的答复。

是的，它选择了商店。

Hello, may I ask if your installation was successful? Does the Xapi service report no error? What is your system configuration like? After I installed it on my Ubuntu18, the Xapi service could not be started, and I have not been able to find a solution.

Do you have all in one server or Mongo is running on its own server ?

[ksourabh45]

Hi all, I was able to fix it. It was due to node libraries version mismatch in xAPI plugin and learning locker.

Hi @looperEit ,

Have you tried with latest ubuntu?

I have had issues with the same and it works with latest version.

Thanks,

您是在一台服务器上拥有所有功能还是在自己的服务器上运行 Mongo？

Yes, I installed all services on one server, including services such as mongoDB and Xapi.
but, I just ran the official wget -qO deployll.sh https://raw.githubusercontent.com/LearningLocker/deploy/master/deployll.sh && bash deployll.sh for automatic installation.

你好@looperEit,

您是否尝试过最新的 ubuntu？

我遇到过同样的问题，它适用于最新版本。

谢谢， 苏拉布

hello, thanks for your replying. Did you mean the ubuntu20? but the official recommendation is to use Ubuntu16 or 18. I have tried to use Ubuntu20, but the installation process prompts to use 18, so I use 18 to complete.

[looperEit]

大家好，我能够修复它。这是由于 xAPI 插件和学习储物柜中的节点库版本不匹配。

Could you please tell me which version I am using? I am using the officially recommended version 14.0 of nodejs.

I have been troubled by this problem for a long time, it is very painful. If you can please tell me your configuration and your known solution, thank you. I have tried to install it many times.

hello？

hello？

I used to, but I decided to go HA, so now the only thing running on my server is nginx and all the LRS roles.

databases are separate, same as statements files and env files.

你好？

我曾经是，但我决定去 HA，所以现在我的服务器上唯一运行的是 nginx 和所有 LRS 角色。

数据库是分开的，与语句文件和环境文件相同。
Have you ever had such a problem? After I opened http://192.168.103.133/data/xAPI, an error of Faithfully yours, nginx. appeared. But I installed it according to the official deployLL.sh. Do I need to adjust the configuration file during the installation process? May I ask if your mongodb is configured on another server, can it run LL normally? Can the statement be sent to LRS normally?
