Hi Harsh,

we need more information from you in order to help. Can you reproduce on demo? Did you have a look at the docs for event queries?

Hi Lars,

It is working fine on demo. But on dev this issue is there. I guess some development is going on in that area…

The ‘issue’ is that on the dev server this URL [ https://play.dhis2.org/dev/api/events? ] does not give the same results that it gives on demo.

On demo, if an event has had data entered then the dataValues fields will contain all the dataValues. But this does not happen on the dev server, Even if an event has data then also the dataValues is just coming as empty tag.

PFA snapshot comparing demo with dev.

Also, adding ‘skipPaging=true’ to the above URL endpoint results in 504 Gateway Time-out. And the instance goes down for a while. This happens on both demo and dev.

Thanks

Hi Harsh,

Yes there is a change with the API. Morten can provide more details on this

For now, you can use the following and get data values api/events.json?fields=:all,dataValues[value,dataElement],notes[value,storedBy,storedDate]

By skipping paging you are literally asking for all events in the db - which is huge and no wonder the time out response. This should be blocked. I mean it shouldn’t be possible to just ask for events without specifying some parameters - for example orgunit, program, tei, enrollment…

···

What is your use-case? Can you limit the search for events?
