Nesting object declaration

can someone help me with the following snippet.

type Item = {    id: number;    size: number;}type Example = {    name: string;    items: [        Item    ];}var obj: Example = {    name: "test",    items: [        {            id: 1,            size: 10        },        {            id: 2,            size: 34        }    ]}

Actually items should be a list of type Item but i got an error.

Type '[{ id: number; size: number; }, { id: number; size: number; }]'is not assignable to type '[Item]'. Source has 2 element(s) buttarget allows only 1.(2322)
