Extracting type from block results in "never", always (hehe)

    Page['blocks']

    is an array, which has no overlap with

    { blockType: "collectionItems" }

    , that's why you get

    never

    .


    What you want is

    Page['blocks'][number]

    to get the elements of the array. This however doesn't work either, because

    Page['blocks']

    is optional. You can fix that with

    NonNullable

    :


    type Hero = Extract<NonNullable<Page['blocks']>[number], { blockType: "collectionItems" }>
