Welcome to the community @Nipun_Dasanayake! 
I think this has to do with some server configuration. Probably with those that have MAX in them. 
@ifoche is very helpful and responds to other community members, so hopefully we’ll find a solution to this issue. 
Thank you!
Thank you very much. Looking forward for the solution.
Hi @Nipun_Dasanayake
I work with @ifoche at EyeSeeTea. I am glad you are also using Bulk Load. Can you let me know your DHIS2 and Bulk Load version? Your problem seems to be related to a performance/RAM issue. Can you try to use Bulk Load 3.19.1 if you are not doing it yet (it comes with several improvements)? It would also help if you can open the browser console and send to us the response of the trackedEntityInstance and event import calls. You said “the system gets stuck”, can you please describe a bit more about what is happening? Does the browser freeze?
Cheers,
Thank you for the reply.
our dhis2 version 2.36.12
bulk load version 3.20.0
page becomes unresponsive. if I, wait it will run eventually.
It showed error in status report, but records were imported, in one instance 8237/8828 were imported. though can not find missing ones.
Client side desktop has enough ram,but chrome uses around 2gb ram
Hi Ifoche,
When I try to download the Tracker program template, I get this error.
“Cannot read properties of null (reading ‘id’)”
What could be the issue?

Andrew
Dear @Nipun_Dasanayake . Some updates to the app happened since your message. I hope your issue was solved. In any case it would be good if you could check it and let us know if later versions work better for you.
In any case, if the page becomes irresponsive, please try uploading less amount of data and let me know if the problem is only happening when you upload big files.
Best regards
Dear @Andrew_Kabala without more details is difficult to say, but could you check if it is a permissions issue? You could try with a superuser and see if the problem is solved. If you didn’t test it, I would also recommend you to test always the latest release (at this moment 3.20.1)
Best regards
Dear @ifoche , I am a super user using the latest version of Bulk Load, when I try to download the template with the Program data model, this is the error that I get.

Andrew
Thank you, @Andrew_Kabala . Is there a way that by DM you could send me some credentials we could use to test it?
I sent you a DM
