Reasons for making this change
When upgrading from an old version I found that our code was creating array schemas in the shape shown in the test case, which was resulting in the
getDefaultFormState
function creating form data that had an array ofundefined
s, instead of usingadditionalItems
as the item schema. This meant that required fields in the array item schema weren't triggering validation errors.Checklist
