Hi devs,

We are currently experiencing an issue in tracker capture (v26)
registration process. When we do a new registration, it actually does
necessary api calls to persist the registration, but front-end web
application stops execution(doesn't show feedback) due to a javascript
exception which throws due to reading an object as an array.

Issue it at line line 1903 services.js branch v26,

1902 : var periods = getEventDuePeriod(null, stage, enrollment);
1903 : newEvent.dueDate = DateUtils.formatFromUserToApi(periods[0].endDate);

However, at line 1826 of services.js in branch v26,

it does following transformation after doing same method call(
getEventDuePeriod) which returns an object,
var prds = getEventDuePeriod(eventsPerStage, programStage, enrollment);
var periods = prds && prds.availablePeriods && prds.availablePeriods.length
? prds.availablePeriods : [];

And does periods.length>0 check before accessing periods[0]. So I believe,
same should be done at 1903.

I think this issue was not there in v25, since getEventDuePeriod() was
actually returning an array.
​
​Please find a screenshot taken during the javascript debug attached with
this email for further clarification.

Kindly let us know if this is an issue in code(services.js), or if this is
an issue in our setup. If you can confirm this is a bug, I can send a PR
with the fix.

Thanks & Regards,
Chathura
