Error on Specifying Filters for Events API

Hello

In version DHIS2 2.36.6 and later versions I get the error Event UIDs and filters can not be specified at the same time when I specify a data element filter in the API call. This works for older versions (2.36.0 and lower). Is this due to any API changes between DHIS2 versions?

Example
Request:

https://play.dhis2.org/2.34.9/api/events?program=IpHINAT79UW&ou=DiszpKrYNg8&fields=dataValues[dataElement,value]&filter=X8zyunlgUfM:eq:Replacement

    "events": [

Thank you for your question @nnkogift! I have asked for support to this and have been trying to investigate it myself as soon as I saw your post. :pray:

Did this ever get reported as a bug? It seems to still be an issue.

I’m actually realizing my response is a bit different… on both the events and tracker/events endpoints, data element filters do not seem to work.

^ works fine.

^ returns nothing

Looking at the documentation, this is the example given: filter=fazCI2ygYkq:eq:PASSIVE
so syntax seems to be correct.

And new tracker endpoint has same behavior
