Aggregate indicators - Issue creating indicator with attribute option combo

Hello,

I’m trying to create an aggregate indicator with attribute option combo following the expression:

#{<dataelement-id>.<categoryoptcombo-id>.<attributeoptcombo-id>}

Its returning Expression is not well-formed.

I’ve tested on:
https://play.dhis2.org/2.33.6, with the formula: #{axVhq1itoQD.HllvX50cXC0.i4Nbp8S2G6A} from EPI Stock form.

Am I forgetting anything?

I check that it works on version 2.29.

Regards,

Damasceno Lopes
