Hello,

i'm getting this error in preview data from aggregates.

"Invalid compiler output, InvalidZip"

Any idea what the cause could be?

Could you share the stacktrace?

Have you update all references etc.

Hi guys!

Did you find a resolution for this issue?

Don't know if this will be of any value to someone, but it seems to have had something to do with me grouping more than once on the same attribute... Sorted that out, and the error went away.

Hi Chris,

Do you mean, group by in an aggregate attribute? Don't know if this is syntactically correct (SQL), but can't find a reason to do this...

What was your use case? Why were grouping twice the same attribute?

Cheers

Chris thanks a bunch, that error has been driving me crazy from my first days at outsystems. Finally did a search and find your answer when I was receiving this error when working with tables that did not any columns with the word "Zip" in them. The Aggregate and SQL widgets interfaces have allot to be desired when there are many columns of interest.

Hi Eduardo!

Yup, I was grouping in entity attributes. I can't quite remember the exact use case, but I think I was probably doing something wrong, as I was able to get the correct list without the offending grouping. As soon as I changed the way in which I was doing the grouping, the error went away.

Thanks!
