CHT's integration with DHIS2 - file containing the dataValueSet doesn't download

I am trying to integrate the CHT with DHIS2 following this guide: DHIS2 Aggregate | Community Health Toolkit
My configuration looks good and I have done the deployment. But the problem is that the file containing the [dataValueSet] does not download when I click on download.

Here is the log i have when i opened the dev console:

Hi @Justinho

I’m sorry the UI is not providing more information about the error that you are encountering. We already have an open issue to improve this: Improve admin export error handling · Issue #6475 · medic/cht-core · GitHub however no delivery date.
In the meantime, could you please check the medic-api logs? You should see an error logged every time you attempt and fail the export.
For example:

2021-11-18 12:37:41 INFO: Export requested for "dhis" 
2021-11-18 12:37:41 INFO:   filters: {
  "dataSet": "VMuFODsyWaO",
  "date": {
    "from": 1634557060169
2021-11-18 12:37:41 INFO:   options: {
  "humanReadable": false
2021-11-18 12:37:41 ERROR: dataSet "VMuFODsyWaO" has no dataElements 

@Justinho Does it work if you manually make the request

@diana The UI is making a request to[dataSet]=hyP81pEpI1Y&filters[date][from]=1637184895072 … Is that the expected path/querystring?
(400 Bad Request)

The former was the expected path in 3.10, but perhaps this pathing has changed in recent versions (this is 3.13).

Looking at the API documentation that looks like a bug in the admin app. I’ll investigate and raise an issue later today.

After investigating locally that funky looking URL is actually correct so it should work.

@diana is correct - there should be an error message in the log. The error should also be visible in the response body. To access this press F12 to load dev tools, go to the Network tab, select the request, select the Response tab, and you should see something like: dataSet "xyz" is not defined.

Thank you for your feedback
@diana here is the error I have in the medic-api log:

yet the dataset has a dataElements in my config:

dhis: {
      dataSet: 'hyP81pEpI1Y',
      dataElement: 'FMIuOQ9vNSM'

@kenn it doesn’t work if I manually make the request


This means that you have no targets configured to use this data element.
Can you please check your target definitions to see if this data set exists? Here is some relevant documentation: DHIS2 Aggregate | Community Health Toolkit and code that gets the targets cht-core/dhis.js at 400fd7658948160b88d2933c1032b3becbe3bae5 · medic/cht-core · GitHub

Hi @diana
I still have the same error:
Here is my config in target.js

module.exports = [
  // Correct indicator 3 (starts at 3)
    id: 'home_visits',
    icon: 'home-visit',
    appliesIf: (contact, report) => getReportHomeVisitSubject(report),
    idType: (contact, report) => {
      if (!contact || ! {
      const familyId = getFamilyIdForContact(contact);
      const visitDate = getReportHomeVisitDate(report);
      return `${familyId}~${visitDate.toFormat('yyyy-MM-dd')}`;
    dhis: {
      dataSet: 'hyP81pEpI1Y',
      dataElement: 'FMIuOQ9vNSM'

In base_settings.json i did this:

"dhis_data_sets": [
      "id": "hyP81pEpI1Y",
      "translation_key": "dhis.dataset.monthly.test"

My code that gets the targets like to cht-core/dhis.js at 400fd7658948160b88d2933c1032b3becbe3bae5 · medic/cht-core · GitHub

Hi @Justinho

I’m going to assume you’re using basicTemplate from muso’s config/. This function ends up stripping your dhis properties from the target. Please try creating the same target without using a template.

@Justinho were you able to upload a target that has the dhis property?

A post was split to a new topic: DHIS2 export json cannot be imported

@Justinho glad you can download your export.
About this other issue, I think we should treat this separately, so I’m splitting it into a new thread.
