Custom expression breaks

Hi there, people!

I’m not quite sure how to call this - therefore, I can’t really search for it. Any help would be appreciated.

I’ll tell you the steps to reproduce the issues:

  • Open the query builder;

  • go for the Sample Dataset, or any of your choice;

  • Select some aggregation, eg. Sum of, without actually selection any column (as if you did that by mistake);

  • Click the “back” icon, and try now to select Custom Expression - the aggregation part of the UI will freeze, and will only be reset when refreshing page.

I could reproduce in 0.31 and 0.32, on both Chrome and Edge.

Check your browser console and you’ll see an error - it’s likely this issue, go and upvote:

You’re the best! Going to upvote that!
