Hi @bridges-wood!

Congratulations, I think you might have found a bug. Looking through the SDK code, I have a theory as to why this might happen.

I still need to reproduce the bug, at which point we can prioritize fixing this. I'll update this issue as we make progress.

Thanks for reporting this!

Here's a follow up for you @bridges-wood.

Cursor support in aggregations is a known limitation. To make this work will require some engineering work. I cannot make any promises on when this work will be prioritized, as we are also working on other query features.
