Dates not saving when creating an assignment

[anabaei]

Hi 

I am creating assignment using this endpoint. It does create assignment but dates are always null! I also changed the type of dates but still no results?

The docs have assignment[due_at].  From your screenshot it looks like you are using due_at.  Have you tried assignment[due_at]?

you are right! it is assignment[due_at]. For some reasons it gave me errors which I had to switch from assignment[due_at] to due_at but the answer you said is correct
