Structure: List items must be an array
The desk structure list takes an array of items. A common mistake is to passing a list of items as arguments instead of an array:
// Incorrect:
S.list()
.title('Content')
.items(
S.listItem().title('Foo'),
S.listItem().title('Bar')
)
// Correct:
S.list()
.title('Content')
.items([
S.listItem().title('Foo'),
S.listItem().title('Bar')
])
