Re: [Dhis2-devs] [d2 lib] - API call failing with "Server connection failed for API request"

[Martin Van Aken]

Ok, sorry, figure it out, just require a "new" as Request is a class:

const req = new d2.analytics.request()
.withProgram('jqKm7VLgdzL')
.addDataDimension(['fyKddt8DF3P', 'RH9knJBq3gv', 'GbtVi9hJhl1',
'pCU50gRMGQh', 'el1mbPDIDSD', 'sn3PEvqjGPp', 'jsZgVNf1fuR'])
.addPeriodDimension([2016, 2017, 2018])
.addOrgUnitDimension(['UpjTv540YGw']);

But this falls back to the same problem as before - getting a server error
("uncaught exception: Server connection failed for API request:") - despite
the exact same request working as a REST call.

Hi Martin

I don't see the "new" in the code you posted.

It should be:
const req = new d2.analytics.request() ...

I guess it depends on which version of DHIS2 you're running.
The specific analytics/geofeature stuff is all new, so no problem with those.
Sorry I don't have a good answer.
Perhaps some backend dev can comment here.

Unfortunately using get() directly does not allow for a list as value
for query parameters.
Only the filter parameter supports an array of values in the form you
tried above.

That's one of the problems that the code for supporting analytics
requests addresses.
You can have a peek at this branch, which we're going to merge into
master soon as it is used by the new Maps app to be released.
https://github.com/dhis2/d2/pull/144

If you can wait some time, I would suggest to use d2.analytics once is
in master.

But, after some more testing, I figured the error I mentioned "409:
Dimension ou is present in
query without any valid dimension options." is not due to encoding
problems but to the fact that in my orgunit tree I don't have LEVEL-6.
So your initial query should work fine (just the ":" was wrong), you
can add more dimension parameters in the query string.

Still it will be much easier to build analytics requests with d2.analytics.

Re: [Dhis2-devs] [d2 lib] - API call failing with "Server connection failed for API request"

[Martin Van Aken]

You are correct for the error message - now putting back a period means
having multiple dimension's - is there any way to put multiple dimension
parameters through the object params? I agree this is much better than
using a long query string, but just using an array as value does not work -
I tried something like:

return getInstance().then(d2 =>
  d2.Api.getApi().get('analytics/events/query/jqKm7VLgdzL', {
stage: 'tbLC6IHktf0',
dimension: ['ou:VAPI4p81HAz;LEVEL-6','xxx'],
displayProperty: 'NAME'
}));

but this is not working. Any clues?

Martin, I found one problem, possibly 2 with your code.
The first one is with the dimension parameter you're passing.

It should be:

dimension=ou:VAPI4p81HAz;LEVEL-6

instead of:

dimension:ou:VAPI4p81HAz;LEVEL-6

The second problem is URL encoding, specifically the ou dimension
query parameter.
The response I get in this case is "409: Dimension ou is present in
query without any valid dimension options."

It's better to pass the query parameters as a object in the 2nd
parameter of the get, so that the Api class takes care of all the URL
encoding, like this:

d2.Api.getApi().get('analytics/events/query/jqKm7VLgdzL', {
stage: 'tbLC6IHktf0',
dimension: 'ou:VAPI4p81HAz;LEVEL-6',
displayProperty: 'NAME'
});

Once I do this, I get a different error about missing start and end
date, which is ok since this endpoint requires those parameters:
https://docs.dhis2.org/master/en/developer/html/webapi_event_analytics.html#webapi_event_analytics_request_query_parameters

Hope this helps,

[Dhis2-devs] [d2 lib] - API call failing with "Server connection failed for API request"

[Martin Van Aken]

Hi,
I'm using d2 to fetch some data inside a DHIS2 app. Everything looks to be
working well, until I have a query using event analytics.

As the d2 lib don't have models yet (I think) for this, I'm making direct
calls using get, for example:

return getInstance().then(d2 =>
d2.Api.getApi().get("events?program=jqKm7VLgdzL"))

This works perfectly, I see the query go through the network view, and the
values get back

Now I'm trying a event analytics query:

return getInstance().then(d2 =>
d2.Api.getApi().get("/25/analytics/events/query/jqKm7VLgdzL?stage=tbLC6IHktf0:ou:VAPI4p81HAz;LEVEL-6=NAME"));

And this show an error in the console with  "Server connection failed for
API request"

I've ran the query through the browser & Postman without any problems. I've
debugged, the authorization header is correct.

Any clue what could go wrong there?

Thanks!

Martin
