Error importing users

hello again, I have to add more than 500 users and try to use the import option, however when I do it I get the following error

Hi @Billy,

When you click on Ayudanos informando sobre este error what information does it show, could you copy paste the information here to give us more information to debug?

Kind Regards,

apparently it is an error because the file is not in the correct format

Yes - that does seem to be the issue, although it should report that error to you rather than showing an error page!

I am filing an issue for this on our tracker, it should be fixed in a patch release on 0.15.x.

For now, make sure that the file you are uploading is a valid CSV file - other file types will not be processed.

I have filed an issue on our Github here: Reporting an error in bulkimportusers triggers an error · Issue #9554 · learningequality/kolibri · GitHub - hopefully we should be able to resolve this by the end of August.

Hello @Bily , looking at your error traceback I see the problem is not in the file format but in the way errors in the file are notified. Your file contains some error that should be shown in the browser. The errors are translated into your server language and it seems the translation is failing.

To try to reproduce it, could you give me more info about your server? kolibri version, Operative system, language (probably es-GT , etc.) ?

I’ve tried to reproduce it using Ubuntu 20.04 and the translation is correct and this error does not appear so I guess you’re using a different system.


Hi @Billy,

@jredrejo has made a fix for what we think was the cause of this, and it should be in the next patch release of Kolibri that will be out in just under two weeks. Thanks for reporting and helping us improve Kolibri!

Kind Regards,
