Hi @judahrand. Thanks for your PR.

I'm waiting for a feast-dev member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Fixes an issue mentioned in #1640 but not the whole issue as this still does not deal with empty lists.

This is great @judahrand!

I'd love to merge this PR, but unfortunately it will probably be blocked by the lack of a test that ensures all our types are working. That isn't really your fault, it's just a technical debt in the project. We still need to write a test that runs through all the types.

Wanted to follow up here. I believe this was already fixed in the main repo (presumably after this PR), so closing this. Thanks again though for adding the fix! We added some basic tests for types, but still a work in progress.
