Hi @JaimeLopez this is the same “manifest” issue that we were discussing in this thread. This is an issue caused by DHIS2, not by Bulk Load but I can confirm this is fixed in, at least, the latest 41 version, that we use internally for a lot of our projects.
According to the release post I linked before it should also be fixed in 40.
I’ve just installed it in this play instance:
And it works without issue.
Are you 100% sure you are at 2.40.8.2?
If it doesn’t work for you in 2.40.8.2 there must be some other difference between the play instance and your instance that it’s causing the issue not to be fixed.
Maybe it is a big ask but do you have a way to copy your system with version 41 and test if it works for you there?
