Can't open About page

Hi all,

In DHIS2 2.33.2, I try to open About page, but it’s just a blank page with error message in console log.
See screenshot:

It’s working fine on

If anyone knows how to fix please share with us.

Hi @em.hispvietnam,

Thanks for reporting your issue.

I see that @Calle_Hedberg and @Timothy_Harding1 had the same issue and reported it on JIRA:

and @taufiqhs and others have had the issue too: RangeError: Invalid Time Value - #5 by jomutsani

I am guessing the reason we cannot reproduce it on the play servers are because those reset every 24 hours.

I’ll follow up with the dev team and report back.


Hi all,

Happy to let you know that a fix for this issue has been merged into all supported versions in DHIS2 and so the About page should load fine in upcoming patch releases.

Thanks @hendrik!

Best regards,

Hi, I’m experiencing this issue on one of my 2.33.4 installations. The other is fine.
I was experiencing it on 2.32 on the same installation as well.

Hi @Edward_Robinson,

Thanks for raising this, I had my colleague @Gintare retest it to make sure the issue hadn’t reoccurred, but everything worked fine for her.

Could it be a different reason (that leads to the same issue?) What kind of console error do you get?

Best regards,

Hi, We get the following:

Let me know if there’s anything more I can do this end?

It appears that it’s the fourth iteration of line 69383 that it fails. It returns the following for the prior 3 before the fourth produces an error:

May 20 2020 19:16:48 GMT+0200 (South Africa) (buildTime?)
May 28 2020 10:52:58 GMT+0200 (South Africa) (serverDate?)
May 28 2020 00:00:00 GMT+0200 (South Africa) (lastAnalyticsTableSuccess?)
?? Invalid Date - I think this is lastSystemMonitoringSuccess
