App connect Group By not returning results

Hello,

I have a select form field whose data source is the following:

However, when I look at the select in the app, it does not return any results.

The select menu populates perfectly when the Group By is removed. So I’m guessing I’m miss-using the Group By somehow.

Any help on this is appreciated.

You can’t use the group by filter like that. What is this data source, where is it coming from and what are you trying to achieve? What values from this data source do you actually need?
