Hi, I'm wondering if

map_task

supports ContainerTask. Looks like this was never merged.

Yes, MapTasks in its current implementation (ArrayNode) supports mapping over plugins beyond just Kubernetes, and that includes ContainerTasks

I got this error though when I tried the following. I'm on flytekit 1.12.3.

Traceback (most recent call last):
