DHIS2 version 2.36.1, Tracker Program attached to a “Category Combination”.
During the Data entry when you try to assign any value, the error message pop-up saying “Failed to update the event in the server An error occurred, please check import summary.”
Error from a browser console says:-
value: “Valid attribute option combo must be specified since program does not have the default category combo”
However, this happens only for desktop version, when I submit data by using Mobile (Android) , there is no problem and submission is super perfect.
On the dhis2 demo (2.36.2) the behavior is the same, I have assigned Category Combination called “Implementing Partner” to a program called “Child Programme”. See the image below
