In the 'Create Task' action, we can’t find the 'Activity Date' field set to a valid date.

Hello, I keep receiving the following error message "Challenge not yet complete in Resilient Hawk Playground

In the 'Create Task' action, we can’t find the 'Activity Date' field set to a valid date.".

However, I am unsure how to resolve this issue. I have attempted to use today and previous dates. I would appreciate any feedback or assistance with where my error may be with this, thank you.
